### What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

### Stay in the loop…

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Subscribe to the feeds.

Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

# Manually Pause/Unpause Firefox Process with POSIX-Signals

Terminal - Manually Pause/Unpause Firefox Process with POSIX-Signals
killall -STOP -m firefox

Manually Pause/Unpause Firefox Process with POSIX-Signals

Continue with:

killall -CONT -m firefox

Useful when having 100+ Tabs open and you temporarily need the power elsewhere.

Be careful - might produce RACE CONDITIONS or LOCKUPS in other processes or FF itself.

matching is case sensitive.

### Know a better way?

If you can do better, submit your command here.

### What others think

Interesting.

Alternatively, exit Firefox and reduce the number of tabs rather than pausing then continuing to use more. :-)

This is great. Do you know how to do this in Windows?

Comment by mawriz 303 weeks and 5 days ago

In fact I do know how to do it in Windows albeit not with onboard tools.

Get

pssuspend

from the "Sysinternals Suite" at MS.

Then put it into your PATH by going to the System Settings.

Edit PATH, append ";c:\path\to\pssuspend.exe" without the quotes

or try this:

Open a commandline window ([Win]+[R] cmd [Enter])

PATH %PATH%;c:\path\to\pssuspend.exe

which is reset on reboot, or if you have the "setx" program also from MS:

setx PATH %PATH%;c:\path\to\pssuspend.exe

now you can do the following from the cmdline:

pssuspend.exe firefox.exe[Enter] pssuspend.exe -r firefox.exe[Enter]

this should do it.

The above warning concerning Lockups is even more relevant to the windows environment, as the only way to suspend a whole process is to walk all the threads and hold them individually is more risky than holding the process all at once. This is because on Windows there is no atomic operation to do this.

There also is "pausep" out there which i haven't tested but should basically do the same.

Worked for me with chromium browser, which creates multiple processes, with dozens of open tabs:

killall -STOP chromium killall -CONT chromium

(-m is not available for me either)
