What are the PowerShell equivalents of Bash's && and || operators?
(4 answers)
Can I get "&&" or "-and" to work in PowerShell?
(13 answers)
Closed 3 years ago.
In bash I use ./task1.sh && ./task2.sh to run task1, and then run task2 as long as task1 did not return an error code. When I try .\task1.bat && .\task2.bat in Powershell I get the error "The Token && Is not a valid separator in this version."
Is there an equivalent for && in Windows Powershell?
This is the closest I can get:
.\task1.ps1 ; if($?){.\task2.ps1}
I think the closest equivalent would be:
.\task1.bat;if($lastexitcode -eq 0){.\task2.bat}
Also, Powershell has -and which you might want to try, but it is not really the same.

On initiating this program i got no output, not even the compiler asked me for input
You're supposed to submit text, not images.
That being said: Your script is fine, but Sublime pipes output to the editor, but isn't a full terminal, so doesn't allow input.
#! /usr/bin/env lua
io.write( 'Enter a number : ' )
local a = io.stdin:read('*n')
while a < 200 do
print( 'value of a :', a )
a = a +1
end
You'll have to open an actual terminal, cd into the relevant directory, then run your script.
chmod +x NAME_OF_SCRIPT.lua && ./NAME_OF_SCRIPT.lua
or
lua NAME_OF_SCRIPT.lua

When to wrap quotes around a shell variable?
(5 answers)
Closed 5 years ago.
I have shell script as below
query="SELECT * from [myDB.myTable]"
echo $(date +"%Y-%m-%d %H:%M:%S")'|'land'|'Failure'|||'twice'|'$query > test.log
When I run above in some directory in my Unix PC, the test.log shows the result as below
2017-12-13 06:54:03|land|Failure|||twice| SELECT temp1.txt test tmp.log tt.sh from [myDB.myTable]
Actually I wanted query to be redirected as it is in the log file, instead it printed all the file names of that directory.
How can I fix this issue?
The dreaded pathname expansion strikes again! You can attribute that list of filenames to having a * in an unquoted expression.
echo "$(date +'%Y-%m-%d %H:%M:%S')'|'land'|'Failure'|||'twice'|'$query" > "test.log"
# ^ ^
cat "test.log"
> 2017-12-13 06:54:03|land|Failure|||twice| SELECT * from [myDB.myTable]
Use double quotes for your complete echo, the single quotes can be deleted:
echo "$(date +"%Y-%m-%d %H:%M:%S")|land|Failure|||twice|${query}" > test.log
I also have put curly braves in ${query}, that is not a solution for your problem but a good habit for future scripts.

How can I escape an exclamation mark ! in cmd scripts?
(4 answers)
Closed 3 years ago.
All,
I have a script that is using plink to connect to ~300 routers. I last used it to update a password for an admin account. Short is, password containing ! is failing.
I can SSH to the router with the password containing ! just can't connect using plink. I have tried replacing ! with %21. Tried escaping with ! and ^!. Nothing is working.
Thoughts?
Yea, that was a lot of nonsense to end-up with double ^
So. Escape ! with ^^
Example
plink -pw abc^^!

Why is terminfo[kcuu1] = '\EOA'?
(1 answer)
Closed 5 years ago.
I'm using xterm. If I type infocmp $TERM | grep end, I see that kend=\EOF. However, if I type read, and then the End key, I see that the sequence \E[F is generated. This seems to be a problem with other keys, too.
Surely the values should be identical??
The terminal can be set on a special mode to send keystrokes from the keypad. You can set that mode by running tput smkx and unset it by tput rmkx.

How to print out the method name and line number and conditionally disable NSLog?
(13 answers)
Closed 9 years ago.
Say I have 10 different implementation files that are run in an chaotic order, and in each of them I have an NSLog(#"Log");, and when I run the program I will get 10 Log's to my console output, but how can I know which one was logged by which file? I'm searching for something like
`In someFile1.m: Log`
`In someFile3.m: Log`
`In someFile2.m: Log`
`...`
And so on and so forth. Is that possible?
You can use preprocessor macros for that, take a look at this example:
NSLog(#"In %s - %s:%d someObject=%#", __FILE__, __func__, __LINE__, someObject);
Here's what's available:
https://developer.apple.com/library/ios/qa/qa1669/_index.html
You can use __FILE__ macro:
NSLog(#"%s",__FILE__ );
Which outputs filename:
