Convert JSON to YAML (unicode safe)
If you tried the other Python version of Convert JSON to YAML and you end up with lines that has "!!python/unicode", this version of the command is for you.

list with full path
List the full path of some files. You can add ".*" on the end if you want to display hidden files.

Extract one file from a remote tar.gz and put it where you want it
This fetches ipfs v0.36.0 for GNU/LInux and puts it in ~/bin without a tmp file or anything else. This works if you already have ~/bin. The `--strip-components=1` flag removes the "kubo" directory in this case. If you have a tar with an even deeper directory structure, say: `some/other/directory/file`, you can just use `--strip-components=3` and it will only extract `file` for you. `-C ~/bin` puts the file in the designated path. In this case, `~/bin`.

Fix subtitle timing (for .sub files)
Fix a microdvd (.sub) subtitle timing by making the phrases to appear 600 frames earlier.

relabel current konsole tab
usage: renam in a script you must replace $PPID with $(awk '{print $4}' /prod/$PPID/stat)

pngcrush all .png files in the directory
Nothing too magical here, just uses pngcrush to losslessly compress all your pngs!

See entire packet payload using tcpdump.
This command will show you the entire payload of a packet. The final "s" increases the snaplength, grabbing the whole packet.

Send email with one or more binary attachments
This command uses mutt to send the mail. You must pipe in a body, otherwise mutt will prompt you for some stuff. If you don't have mutt, it should be dead easy to install.

Expand shortened URLs
curl(1) is more portable than wget(1) across Unices, so here is an alternative doing the same thing with greater portability. This shell function uses curl(1) to show what site a shortened URL is pointing to, even if there are many nested shortened URLs. This is a great way to test whether or not the shortened URL is sending you to a malicious site, or somewhere nasty that you don't want to visit. The sample output is from: $ expandurl http://t.co/LDWqmtDM

list files recursively by size
