I'm trying to use external script with variables, but in result I get only "no such file or directory".
1st.ksh
#!bin/ksh
PATHNAME = `dirname $0`
. $PATHNAME/2nd.ksh
Echo $EXTVAR
2nd.ksh
#!bin/ksh
EXTVAR=1
I tried to use "Source" instead of "." (Source $PATHNAME/2nd.ksh) and I get the same result.
To run script I'm using full path to the script - cygdrive/e/Folder/1st.ksh.
2nd.ksh in this path too (cygdrive/e/Folder/).
All rights was granted for both files (chmod u=rwx,g=rwx,o=rwx filename).
If I put files in cygwin home path (/home/username/) I have the same.
Please help to understand what I'm doing wrong.
Thanks in advance!
$() should be used in ksh instead of `` (link)
. should be user instead of source (link)
"=" must not be surrounded with spaces. You should write: PATHNAME=$(dirname $0)
you should be aware of case-sensitiveness: echo, source

How can I find out (with Windows a batch command), if, for example, a variable starts with ABC?
I know that I can search for variables if I know the whole content (if "%variable%"=="abc"), but I want that it only looks after the beginning.
I also need it to find out where the batch file is located, so if there is a other command that reveals the file's location, please let me know.
Use the variable substring syntax:
IF "%variable:~0,3%"=="ABC" [...]
If you need the path to the batch file without the batch file name, you can use the variable:
%~dp0
Syntax for this is explained in the help for the for command, although this variable syntax extends beyond just the for command syntax.
to find batch file location use %0 (gives full patch to current batch file) or %CD% variable which gives local directory
I've got following line in my script
exec $::env(PATH)/program.exe
In my env PATH variable I've got a directory where I've got this executable file. For example:
PATH env variable got among other this - D:\my_program\bin
I've got error:
Error:
couldn't execute C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;D:\my_program\bin;\program": no such file or directory
Any suggest how to execute .exe file using system variable like PATH in tcl?
Thanks
PS
OK, when I've create a new env variable (PATH1 - without any other paths, just one) and set .exe file path to it, it seems to work. Any solution to do with PATH (with multiple paths) excluding set D:\my_program\bin in first place?
You should simply use the Tcl library function made for this auto_execok.
Try this:
exec {*}[auto_execok program.exe]
It automatically searches the PATH and constructs the right path for using with exec.
For example, to start notepad.exe:
% auto_execok notepad.exe
C:/windows/system32/notepad.exe
% exec {*}[auto_execok notepad.exe]
To see why the {*} is needed, have a look at http://wiki.tcl.tk/765. Basically auto_execok is pretty smart and can return a list, if needed, e.g. for running start on windows, which needs the expansion to work properly with exec.
I found the following code snippet on the internet, and want to use it in my own .vimrc.
augroup CodeFormatters
autocmd!
autocmd BufReadPost,FileReadPost *.py :silent %!PythonTidy.py
augroup END
However, I'm not quite sure where to put the PythonTidy.py script, so that it is accessible from everywhere.
Furthermore I read that using BufReadPre is better than BufReadPost, respectively FileReadPre, is that true?
As it stands, PythonTidy.py must be accessible through your PATH. If you have a convenient place already contained in there, e.g. ~/bin, just place it there.
Alternatively, you can place it somewhere into your .vim directory, and use something like expand('<sfile>:p:h') to resolve the directory of your Vimscript, and build a relative path from there.
As you want to filter the read buffer contents with the :%! command, you have to use the BufReadPost event; with BufReadPre, the buffer hasn't yet been read and nothing would be sent to the filter.
PythonTidy is a command line executable: put it somewhere in your $PATH.
You can also put it anywhere and use an absolute path in the autocmd:
autocmd BufReadPost,FileReadPost *.py :silent %!/path/to/PythonTidy.py
I'm working on a script that processes a folder and there is always one file in it I need to rename. The new name should be the parent directory name. How do I get this in a batch file? The full path to the dir is known.
It is not very clear how the script is supposed to become acquainted with the path in question, but the following example should at least give you an idea of how to proceed:
FOR %%D IN ("%CD%") DO SET "DirName=%%~nxD"
ECHO %DirName%
This script gets the path from the CD variable and extracts the name only from it to DirName.
You can use basename command:
FULLPATH=/the/full/path/is/known
JUSTTHENAME=$(basename "$FULLPATH")
You can use built-in bash tricks:
FULLPATH=/the/full/path/is/known
JUSTTHENAME=${FULLPATH##*/}
Explanations:
first # means 'remove the pattern from the begining'
second # means 'remove the longer possible pattern'
*/ is the pattern
Using built-in bash avoid to call an external command (i.e. basename) therefore this optimises you script. However the script is less portable.
The company I work for prefixes all their admin level accounts with a $ sign. Trouble, I know.
I'm trying to use test-path to see if a folder exists like so:
$username = read-host "Enter Login ID:"
I type $adminsdb into the box and hit ok
##### Find TS Profile #####
$TSProfile_exist = test-path "\\server\tsprofiles$\$username"
The folder DOES exist but... $TSProfile_exist is coming up False
How do I handle the $ in the username? I'm building this app to bring up quick stats on users in the environment. We also have service accounts that are prefixed with # signs.
The way to handle special caracters in PowerShell is using ` (backtick)
$TSProfile_exist = test-path "\\server\tsprofiles$\$username"
becomes
$TSProfile_exist = test-path "\\server\tsprofiles`$\$username"
Be careful a trick with Test-Path, is that it semantic is not that the directory exists, but is that the directory is readable. In other words if you do not have access to the directory you test, you will receive false even if the directory exists. See this other entry.
The other alternative is to use single-quoted strings; powershell will not expand variables in this case.
test-path '\\server\path\$username'
