  • I absolutely love this website, and appreciate every contribution. This is the first place I go when I'm stuck, you all have some great ideas. But contributions seem to be slipping a little. If all of us could contribute more code from time to time, this site would be absolutely incredible. Since I'm a relative newcomer to commandline-fu, I don't have the knowledge to contribute much, but I will do what I can.

    /bin/bash echo -n "Let's POST MORE, PLEASE!"

What's this? is the place to record those command-line gems that you return to again and again. 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.

Check These Out

Ping a URL sending output to file and STDOUT
The tee (as in "T" junction) command is very useful for redirecting output to two places.

Outputs each arg on its own line
This can be useful for transforming command-line args into input for xargs (one per line). This can also be done with ls if the args are filenames, but that's getting awfully close to Useless Use of Cat territory (

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Recursive search and replace (with bash only)
Replaces a string matching a pattern in one or several files found recursively in a particular folder.

ping with timestamp

check open ports without netstat or lsof

background a wget download

Display / view the contents of the manifest within a Java jar file
Displays the manifest within a jar file. Can use it to confirm version number, etc.

Print every Nth line
Sometimes commands give you too much feedback. Perhaps 1/100th might be enough. If so, every() is for you. $ my_verbose_command | every 100 will print every 100th line of output. Specifically, it will print lines 100, 200, 300, etc If you use a negative argument it will print the *first* of a block, $ my_verbose_command | every -100 It will print lines 1, 101, 201, 301, etc The function wraps up this useful sed snippet: $ ... | sed -n '0~100p' don't print anything by default $ sed -n starting at line 0, then every hundred lines ( ~100 ) print. $ '0~100p' There's also some bash magic to test if the number is negative: we want character 0, length 1, of variable N. $ ${N:0:1} If it *is* negative, strip off the first character ${N:1} is character 1 onwards (second actual character).

Using Git, stage all manually deleted files.
You'll probably want to pass in the -rf options if you have to delete a directory or something.
