  • Automator Bash script to create Clean zips in MacOS Finder without __MACOSX metadata

    Finder compresses to ZIP but always includes extraneous metadata files (__MACOSX and .DS_Store) files and folders that may confuse other programs. One alternative is creating them and then editing the ZIP. This can work standalone or in an automator script accepting multiple selections (files or folders) and creating one zip per argument/selected file without that metada.

  • Use jq to validate and pretty-print json output

    The `jq` tool can also be used do validate json files and pretty print output: ` jq < file.json` Available on several platforms, including newer debian-based systems via `#sudo apt install jq`, mac via `brew install jq`, and from source https://stedolan.github.io/jq/download/ This alternative to the original avoids the useless use of cat Show Sample Output

  • Convert hex data to binary with a bash function (requires bash v4+ for the @^^ lowercase hex demangling)

Show Sample Output

What's this?

commandlinefu.com 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

Archive all folders in a directory into their own tar.bz2 file
Remove the "echo" to actually archive. Many similar commands are found on commandlinefu but I end up needing this very specific one from time to time. To extract any of them, use the standard tar.bz2 extract command: $tar xvjf folder1.tar.bz2

Convert mkv to SVCD/DivX
ffmpeg supports mkv

Change pidgin status
Changes pidgin status using its dbus interface. The status code can be obtained using command #4543.

Delete all files in a folder that don't match a certain file extension
Deletes all files in a folder that are NOT *.foo, *.bar or *.baz files. Edit the pattern inside the brackets as you like.

Get size of terminal

Get a facebook likes quantity from CLI
Replace the with your URL, for example http://rublacklist.net/12348/ and it will show likes number

Use a var with more text only if it exists
See "Parameter Expansion" in the bash manpage. They refer to this as "Use Alternate Value", but we're including the var in the at alternative.

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Show every subdirectory (zsh)

Bash logger
