Search for MP3s from current directory and play them in random order.

This uses bash's Process Substitution. It is necessary to give the full path of the file, thus why the filenames are filtered through realpath. In theory, this command should also work with mplayer and mplayer2 (using -playlist instead of --playlist). Modifications: - You can search specific directories by inserting them between "find" and "-type". - Edit the parameter of "-iname" to change the type of file searched for. - Remove everything after "realpath" to play the files in order.

Compare directories (using cmp to compare files byte by byte) to find files of the same name that differ

Compare the content of the files in the current directory with files of the same name in the duplicate directory. Pop Quiz: You have a duplicate of a directory with files of the same name that might differ. What do you do? You could use diff to compare the directories, but that's boring and it isn't as clever as find -print0 with xargs. Note: You must omit stderr redirect 2>/dev/null to see the list of missing files from DUPDIR, if any. Hint: Redirect stderr to a new file to produce a more readable list of files that are missing from DUPDIR. Warning: This doesn't tell you if DUPDIR contains files not found in the current directory so don't delete DUPDIR. Show Sample Output
This is sample output - yours may be different.
```
./DIFFER.PNG /DUPDIR/./DIFFER.PNG differ: char 59, line 3

Cleanup remote git repository of all branches already merged into master

This is useful in teams where developers don't bother to remove branches after merging PR. These branches make it hard to seek for really useful branches, which gives us a nice value of finding and exploring other people's code even before they create PR for it.

Get a list of stale AWS security groups

AWS provides a method to audit for obsolete AWS security groups. From their documentation: "Describes the stale security group rules for security groups in a specified VPC. Rules are stale when they reference a deleted security group in a peer VPC, or a security group in a peer VPC for which the VPC peering connection has been deleted." Show Sample Output

Rename files in batch

Play all the music in a folder, on shuffle

Play files in shuffle mode with bash and mpg123. Why bother using big-as-hell stuff like mplayer? This will play all your music files contained in */* (in my case author/song.format) with bash and mplayer showing a nice output.

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Arch Linux: Search for missing libraries using pacman

If, while using a program, you get an error similar to: error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory Use pacman or pkgfile to search for the package that owns the missing library https://wiki.archlinux.org/index.php/General_troubleshooting#Message:_%22error_while_loading_shared_libraries%22

Command line calculator

This function defines a command line calculator that handles everything pythons math module can handle, e.g. trigonometric functions, sqrt, log, erf, ... (see http://docs.python.org/library/math.html). It even knows about the constants pi and e.

Find the process you are looking for minus the grepped one

As an alternative to using an additional grep -v grep you can use a simple regular expression in the search pattern (first letter is something out of the single letter list ;-)) to drop the grep command itself.

Prepend a text to a file.

The original command is great, but I often want to prepend to every line.

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).
