A thread at /r/linux sought out to reveal all the magic ways of increasing productivity under Linux (or other *nix based OS-es), and as most people I thought that there wouldn’t be much news here.
But I was wrong. So very, very wrong.
- disown – a way to disown a process, making it continue running in the background if you have to log out or close a long running session over ssh because you’re going somewhere, but want to keep the currently running process still running. If you’ve ever thought “why the fsck didn’t I run this under screen?”, then this trick is for you. This is a new future, and I’m proud to be a part of it.
- CTRL+r in bash – allows you to search your bash history buffer. I’ve known about this, I’ve just never picked up the habit of actually using it. Will do that now.
- ssh-copy-id – Appends your public key to the authorized_keys file at the destination computer.
- man ascii – the manual page entry for ascii contains an ascii table, right there in your terminal.
- xargs ‐‐max-procs and parallel – allows you to duplicate the functionality of xargs, but in parallel. Starts up all the processes at the same time, instead of starting them one by one.
Head over to the thread for other goodies such as a sudo alias for writing files when you’ve opened them without the correct permissions directly in vim.
