Why is linux ignored

This allows you to check the return code in subsequent steps and handle it programmatically. Show 1 more comment. Just add true after the command where you want to ignore the error. Lars Kotthoff Lars Kotthoff k 13 13 gold badges silver badges bronze badges.

I think it's important to add this: this method will allow the response code and error message to persist, whereas the "! This is important when using set -e and trying to capture an error message: e. Arslan Qadeer Arslan Qadeer 1, 1 1 gold badge 7 7 silver badges 5 5 bronze badges. Non zero exit codes are captured though. Any idea why? Ankita13 Because if it was zero the first command was successful and there is need to run what's after.

I have used this technique to force stop a Gitlab CI job manually because the command I was running seemed to hang even if the exit code was 1, so I ended up doing the exit myself. More concisely:!

This just inverts exit code of a command, so command that finished successfully will return 1 instead of 0 and fail script with -e. My understanding is that the! This script displays the message Still alive!

Are you seeing different behavior? I was inattentive. I'm using RHEL 7. When using - or -l you invoke an interactive login shell for the specified user. Depending on what the shell initialization files do for the given user, the command may not be executed.

For example, if they re-execute a shell using exec without passing the command line parameters from the invoking shell , either directly or through something like tmux or ssh-agent , then the command string would be lost. Provide an environment similar to what the user would expect had the user logged in directly.

Don't use - hyphen after su. Simply run su demo -c 'ls -la' When you invoke '-' with su, It initializes user profile and environment. There must be some script within profile which is not letting user shell to reach at the end. Sign up to join this community. I could not find this information on their website.

The desktop Linux side is virtually invisible. What surprises me that Ubuntu stays absent from the Linux Foundation events. They should at least regularly donate to these organizations. They should also give desktop Linux projects some weightage in their events. Microsoft Windows rules the PC sector because almost all major manufacturers have tailored their hardware to support the Windows operating system.

This positive change has nothing to do with Linux Foundation, but this is something they could have done in the past. I want to send little script to remote machine by ssh the script is!

You can send this: ssh But what did the trick here is to invert the comas changing ' with " and viceversa. What about googleing "bash more than one command in one line"? This allows the kernel to select the proper executable loading routines depending on the binary executable format and what allows you for example to execute BSD programs in linux kernels, and viceversa A special value for this magic numbers is composed by the two characters and!

NOTE Its important to ensure you'll execute the whole thing, so it's best to pass all the script contents in the destination target, and once assured you have passed the whole thing to execute it as a whole.
