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.

UpGuard checks and validates configurations for every major OS, network device, and cloud provider.

Stay in the loop…

Follow the Tweets.

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.

Find files that were modified by a given command

This has helped me numerous times trying to find either log files or tmp files that get created after execution of a command. And really eye opening as to how active a given process really is. Play around with -anewer, -cnewer & -newerXY


There are 5 alternatives - vote for the best!

Terminal - Alternatives
strace <name of the program>

Know a better way?

If you can do better, submit your command here.

What others think

Great command!

Another way could also use strace. strace records all system calls made, and you can even attach it to running processes:

strace -o straceoutput.txt $COMMAND

also use -p $PID to attach to an already-running program. Also, use ltrace to trace library calls.
