delay: a simple scheduler

the "delay" utility is an invaluable tool for me. with gnu-screen it allows you to schedule something and have it run and output to the current terminal, unlike "at". You can also use it like "sleep" with seconds and also with date: delay until 13:33 friday && echo test get it from: http://onegeek.org/~tom/software/delay/current/delay.c (author: Tom Rothamel)

Parallel XZ with progress bar

You need: pxz for the actual work (http://jnovy.fedorapeople.org/pxz/). The function could be better with better multifile and stdin/out support.

how to export a table in .csv file

Exports the result of query in a csv file

Python extract json

copy from host1 to host2, through your host

Good if only you have access to host1 and host2, but they have no access to your host (so ncat won't work) and they have no direct access to each other.

Generate a random password 30 characters long

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

List all open ports and their owning executables

Particularly useful on OS X where netstat doesn't have -p option.

Extract the MBR ID of a device

Useful when you want to know the mbrid of a device - for the purpose of making it bootable. Certain hybridiso distros, for eg the OpenSUSE live ISO uses the mbrid to find the live media. Use this command to find out the mbrid of your USB drive and then edit the /grub/mbrid file to match it.

Advanced python tracing

Trace python statement execution and syscalls invoked during that simultaneously

Maximum PNG compression with optipng, advpng, and advdef

optipng and advancecomp (for the the advpng and advdef tools) are the best FOSS tools for losslessly compressing PNGs. With the above tool chain, you can cut off as much as 20% off a PNG's file size.

View any already in progress copy command in detail

If you spot a dubious looking cp command running you can use this command to view what is being copied and to where. 1234 is the PID of the cp command being passed to the lsof utility. 3r.*REG will display the file/directory that is being read/copied. 4w.*REG will display the destination it is being written to.
