  • 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.

Check These Out

Print github url for the current url
Works for repos cloned via ssh or https.

Backup all MySQL Databases to individual files
No need to loop when we have `xargs`. The sed command filters out the first line of `show databases` output, which is always "Database".

print line and execute it in BASH
!# is the currennt line so far, by using !#:- you can go from the second arg (it's zero indexed) to the last ($) (did I understand the problem correctly?)

A DESTRUCTIVE command to render a drive unbootable
Overwrites the boot sector. Since this doesn't overwrite any data, you can usually recover by re-creating the partition table exactly the same as before you zeroed it. This can also help sometimes if you install a new drive in a Windows machine which can't read it.

Convert filenames from ISO-8859-1 to UTF-8
Nothing advanced, it just finds filenames that are stored with ISO-8859-1 characters and and converts those into UTF-8. Recommended to use without the --notest flag first so you can see what will be changed.

View non-printing characters with cat
Useful to detect number of tabs in an empty line, DOS newline (carriage return + newline). A tool that can help you understand why your parsing is not working.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Simple top directory usage with du flips for either Linux or base Solaris
No need to type out the full OR clause if you know which OS you're on, but this is easy cut-n-paste or alias to get top ten directories by singleton. To avoid the error output from du -xSk you could always 2>/dev/null but you might miss relevant STDERR.

lotto generator

Notepad in a browser (type this in the URL bar)
It doesn't save your notes, but it's great for jotting something down quickly.
