All I can find on this topic is mentions of FSMoveObjectToTrashSync function, which is now deprecated and no alternative is listed for it.
How to do it from C or Objective-C code?
Use NSFileManager:
https://developer.apple.com/documentation/foundation/nsfilemanager
trashItemAtURL:resultingItemURL:error:
Moves an item to the trash.
In C, you can use AppleScript to move files to the trash. Here's a simple example:
#include <stdio.h>
#include <stdlib.h>
#define PATH "/tmp/"
#define NAME "delete-me.txt"
int main() {
int status;
/* Create a file */
FILE *f;
f = fopen(PATH NAME, "w");
if (!f) {
fputs("Can't create file " PATH NAME "\n", stderr);
return 1;
}
fputs("I love trash\n", f);
fclose(f);
/* Now put it in the trash */
status = system(
"osascript -e 'set theFile to POSIX file \"" PATH NAME "\"' "
"-e 'tell application \"Finder\"' "
"-e 'delete theFile' "
"-e 'end tell' "
">/dev/null"
);
if (status == 0) {
puts("Look in the trash folder for a file called " NAME);
}
else {
puts("Something went wrong. Unable to delete " PATH NAME);
}
return 0;
}
A few notes:
Multi-line scripts have to be sent as multiple -e command line options.
Since osascript insists on printing status messages to the command line console, I've redirected its output to /dev/null. But, if a file of the same name already exists in the trash, then the deleted file will be renamed. If you need to know this name, you'll have to use popen() instead of system() and parse the return string from osascript.
I wrote the following code in a file named test.cpp on godaddy web host:
#include <iostream>
using namespace std;
int main () {
cout << "Content-type:text/html\r\n\r\n";
cout << "<html>\n";
cout << "<head>\n";
cout << "<title>Hello World - First CGI Program</title>\n";
cout << "</head>\n";
cout << "<body>\n";
cout << "<h2>Hello World! This is my first CGI program</h2>\n";
cout << "</body>\n";
cout << "</html>\n";
return 0;
}
And I compile test.cpp on the godaddy host using "g++ test.cpp -o a.cgi".
Then I tried to access the cgi (type "www.XXX.com/a.cgi"), the error code 500 came out. I have no idea what went wrong.
Change the permissions of the file using file manager to make it executable
try www.xxx.com/cgi-bin/a.cgi
changing a.cgi to a.cpp and then check if it works
I have searched Google and Stackoverflow for an answer to the question of how to code the equivalent of
git commit -a -m "message"
in libgit2 (https://libgit2.github.com) and C or C++.
But I cannot find a ready and working answer to this question.
I am using libgit2-0.21.
Below is code that initializes a git repository, adds two files to it, and stages the two files so they are ready to be committed.
My question is how to code "git commit -a -m "msg" in libgit2?
#include <sys/stat.h>
#include <string>
#include <fstream>
#include <iostream>
#include <git2.h>
using namespace std;
int main (int argc, char** argv)
{
git_threads_init ();
// Create repository directory.
string directory = "repository";
mkdir (directory.c_str(), 0777);
// Initialize the repository: git init.
git_repository *repo = NULL;
int result = git_repository_init (&repo, directory.c_str(), false);
if (result != 0) cerr << giterr_last ()->message << endl;
// Store two files in the repository directory.
ofstream file;
file.open ("repository/file1", ios::binary | ios::trunc);
file << "Contents of file one";
file.close ();
file.open ("repository/file2", ios::binary | ios::trunc);
file << "Contents of file two";
file.close ();
// Run the equivalent of "git add ."
// Get the git index.
git_index * index = NULL;
result = git_repository_index (&index, repo);
if (result != 0) cerr << giterr_last ()->message << endl;
// Add all files to the git index.
result = git_index_add_all (index, NULL, 0, NULL, NULL);
if (result != 0) cerr << giterr_last ()->message << endl;
// Write the index to disk.
result = git_index_write (index);
if (result != 0) cerr << giterr_last ()->message << endl;
// Run the equivalent of "git commit -a -m "commit message".
// How to do that through libgit2?
// Run "git status" to see the result.
system ("cd repository; git status");
// Free resources.
git_index_free (index);
git_repository_free (repo);
git_threads_shutdown ();
return 0;
}
The code can be compiled as follows:
g++ -Wall -I/opt/local/include -L/opt/local/lib -lgit2 -o test git.cpp
Below is the output of running the compiled binary:
On branch master
Initial commit
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: file1
new file: file2
Once the index is updated
create a tree from it through git_index_write_tree()
create a commit that references this tree through git_commit_create_v()
See this end to end test which performs the equivalent of the following
$ echo "test" > test.txt
$ git add .
$ git commit -m "Initial commit"
I have now whittled this down to a minimal test case. Thus far I have been able to determine that this is an issue related to pseudo-terminals which come about with the pipe of ssh. Adding the '-t -t' to the ssh call improved things, in that now, it takes a second call to fgets() to cause the issue. I suspect that the stderr output of the ssh command somehow works into the issue, for now I have redirected stderr to stdout in the ssh code to execute. I do wonder if the "tcgetattr: Invalid argument" error is part of the problem, but am not sure how to get rid of that. It seems to come from the -t -t being present. I believe the -t -t is moving in the right direction, but I have to set up the pseudo terminal for stderr somehow and perhaps the test will work properly?
The Makefile:
test:
gcc -g -DBUILD_MACHINE='"$(shell hostname)"' -c -o test.o test.c
gcc -g -o test test.o
.PHONY: clean
clean:
rm -rf test.o test
The test.c source file:
#include <unistd.h>
#include <string.h>
#include <stdio.h>
int
main(int argc, char *argv[])
{
const unsigned int bufSize = 32;
char buf1[bufSize];
char buf2[bufSize];
int ssh = argv[1][0] == 'y';
const char *cmd = ssh ? "ssh -t -t " BUILD_MACHINE " \"ls\" 2>&1" : "ls";
FILE *fPtr = popen(cmd, "r");
if (fPtr == NULL) {
fprintf(stderr,"Unable to spawn command.\n");
perror("popen(3)");
exit(1);
}
printf("Command: %s\n", cmd);
if (feof(fPtr) == 0 && fgets(buf2, bufSize, fPtr) != NULL) {
printf("First result: %s\n", buf2);
if (feof(fPtr) == 0 && fgets(buf2, bufSize, fPtr) != NULL) {
printf("Second result: %s\n", buf2);
int nRead = read(fileno(stdin), buf1, bufSize);
if (nRead == 0) {
printf("???? popen() of ssh consumed the beginning of stdin ????\n");
} else if (nRead > 0) {
if (strncmp("The quick brown fox jumped", buf1, 26) != 0) {
printf("??? Failed ???\n");
} else {
printf("!!!!!!! Without ssh popen() did not consume stdin !!!!!!!\n");
}
}
}
}
}
This shows it running the passing way:
> echo "The quick brown fox jumped" | ./test n
Command: ls
First result: ARCH.linux_26_i86
Second result: Makefile
!!!!!!! Without ssh popen() did not consume stdin !!!!!!!
This shows it running the failing way:
> echo "The quick brown fox jumped" | ./test y
Command: ssh -t -t hostname "ls" 2>&1
First result: tcgetattr: Invalid argument
Second result: %backup%~ gmon.out
???? popen() of ssh consumed the beginning of stdin ????
Okay, I have got this working finally. The secret was to supply /dev/null as the input to my ssh command as follows from the test case above:
const char *cmd
= ssh ? "ssh -t -t " BUILD_MACHINE " \"ls\" 2>&1 < /dev/null" : "ls";
However, while the code works correctly, I get a nasty message which apparently I can ignore for my purposes (although I'd like to make the message go away):
tcgetattr: Inappropriate ioctl for device
I need a command line tool to dump standard Windows DLL version info so I can process it by means of a bash script (Cygwin).
As a Java developer I am not very used to Microsoft development tools (though I have a little bit of experience with Microsoft Visual Embedded C++ 4.0 and Microsoft Visual Basic 6.0).
The appropriate tool seems to be mt.exe, as stated on SO. However the only chance I have found to get this little application is to download a 1.29 GB ISO of the Windows SDK for Windows Server 2008 and .NET Framework. I can not believe this is the only way to do it.
I have also found a little application on the Internet called PEView, but it displays too much (and useless in my case) information and it is not a command line application.
Standard objdump bundled inside Cygwin can also dump some information about the DLL files, but I can not see the option to dump DLL version. Note that MajorImageVersion, MinorImageVersion and other fields dumped by this tool (with -p option) are not related to own DLL version.
Any alternatives about what to do? Maybe I missed some important objdump option? Is mt.exe my only choice? If this is the case, is it possible to get it separately from Windows SDK?
You can use PowerShell to get the information you want.
(Get-Item C:\Path\To\MyFile.dll).VersionInfo
By default this will display ProductVersion and FileVersion
But the full VERSIONINFO is available. I.e. to return Comments
(Get-Item C:\Path\To\MyFile.dll).VersionInfo.Comments
Use Microsoft Sysinternals Sigcheck.
This sample outputs just the version:
sigcheck -q -n foo.dll
Unpacked sigcheck.exe is only 228 KB.
You can write a VBScript script to get the file version info:
VersionInfo.vbs
set args = WScript.Arguments
Set fso = CreateObject("Scripting.FileSystemObject")
WScript.Echo fso.GetFileVersion(args(0))
Wscript.Quit
You can call this from the command line like this:
cscript //nologo VersionInfo.vbs C:\Path\To\MyFile.dll
C:\>wmic datafile where name="C:\\Windows\\System32\\kernel32.dll" get version
Version
6.1.7601.18229
You can also look at filever.exe, which can be downloaded as part of the Windows XP SP2 Support Tools package - only 4.7MB of download.
or you can build one yourself. Open VS, create a new console application. Create a simple project with no ATL or MFC support, leave the stdafx option checked but do not check 'empty project' and call it VersionInfo.
You'll get a simple project with 2 files: VersionInfo.cpp and VersionInfo.h
Open the cpp file and paste the following into it, then compile. You'll be able to run it, first argument is the full filename, it'll print out "Product: 5.6.7.8 File: 1.2.3.4" based on the Version resource block. If there's no version resource it'll return -1, otherwise 0.
Compiles to an 8k binary using the dll CRT, 60k with everything linked statically (set in the C++ options, change "Code Generation page, Runtime options" to "/MT")
HTH.
PS. If you don't want to use Visual Studio, it'll still compile using any c++ compiler (fingers crossed), but you'll almost certainly have to change the #pragma - just specify that lib in the linker settings instead, the pragma's just a shorthand to automatically link with that library.
// VersionInfo.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <windows.h>
#pragma comment(lib, "version.lib")
int _tmain(int argc, _TCHAR* argv[])
{
DWORD handle = 0;
DWORD size = GetFileVersionInfoSize(argv[1], &handle);
BYTE* versionInfo = new BYTE[size];
if (!GetFileVersionInfo(argv[1], handle, size, versionInfo))
{
delete[] versionInfo;
return -1;
}
// we have version information
UINT len = 0;
VS_FIXEDFILEINFO* vsfi = NULL;
VerQueryValue(versionInfo, L"\\", (void**)&vsfi, &len);
WORD fVersion[4], pVersion[4];
fVersion[0] = HIWORD(vsfi->dwFileVersionMS);
fVersion[1] = LOWORD(vsfi->dwFileVersionMS);
fVersion[2] = HIWORD(vsfi->dwFileVersionLS);
fVersion[3] = LOWORD(vsfi->dwFileVersionLS);
pVersion[0] = HIWORD(vsfi->dwProductVersionMS);
pVersion[1] = LOWORD(vsfi->dwProductVersionMS);
pVersion[2] = HIWORD(vsfi->dwProductVersionLS);
pVersion[3] = LOWORD(vsfi->dwProductVersionLS);
printf("Product: %d.%d.%d.%d File: %d.%d.%d.%d\n",
pVersion[0], pVersion[1],
pVersion[2], pVersion[3],
fVersion[0], fVersion[1],
fVersion[2], fVersion[3]);
delete[] versionInfo;
return 0;
}
Using Powershell it is possible to get just the Version string, i.e. 2.3.4 from any dll or exe with the following command
(Get-Item "C:\program files\OpenVPN\bin\openvpn.exe").VersionInfo.ProductVersion
Tested on Windows 10
The listdlls tools from Systernals might do the job: http://technet.microsoft.com/en-us/sysinternals/bb896656.aspx
listdlls -v -d mylib.dll
This function returns the ntfs Windows file details for any file using Cygwin bash (actual r-click-properties-info) to the term
Pass the files path to finfo(), can be unix path, dos path, relative or absolute. The file is converted into an absolute nix path, then checked to see if it is in-fact a regular/existing file. Then converted into an absolute windows path and sent to "wmic". Then magic, you have windows file details right in the terminal. Uses: cygwin, cygpath, sed, and awk. Needs Windows WMI "wmic.exe" to be operational. The output is corrected for easy...
$ finfo notepad.exe
$ finfo "C:\windows\system32\notepad.exe"
$ finfo /cygdrive/c/Windows/System32/notepad.exe
$ finfo "/cygdrive/c/Program Files/notepad.exe"
$ finfo ../notepad.exe
finfo() {
[[ -e "$(cygpath -wa "$#")" ]] || { echo "bad-file"; return 1; }
echo "$(wmic datafile where name=\""$(echo "$(cygpath -wa "$#")" | sed 's/\\/\\\\/g')"\" get /value)" |\
sed 's/\r//g;s/^M$//;/^$/d' | awk -F"=" '{print $1"=""\033[1m"$2"\033[0m" }'
}
There is an command line application called "ShowVer" at CodeProject:
ShowVer.exe command-line VERSIONINFO display program
As usual the application comes with an exe and the source code (VisualC++ 6).
Out outputs all the meta data available:
