Check These Out

Run a ext4 file system check and badblocks scan with progress info
Nothing fancy, just a regular filesystem scan that calls the badblocks program and shows some progress info. The used options are: -c ? check for bad sectors with badblocks program -D ? optimize directories if possible -f ? force check, even if filesystem seems clean -t ? print timing stats (use -tt for more) -y ? assume answer ?yes? to all questions -C 0 ? print progress info to stdout /dev/sdxx ? the partition to check, (e.g. /dev/sda1 for first partition on first hard disk) NOTE: Never run fsck on a mounted partition!

fetch all revisions of a specific file in an SVN repository
exported files will get a .r23 extension (where 23 is the revision number)

list block devices
Shows all block devices in a tree with descruptions of what they are.

tar+pbzip2 a dir

Find all the files more than 10MB, sort in descending order of size and record the output of filenames and size in a text file.
This command specifies the size in Kilobytes using 'k' in the -size +(N)k option. The plus sign says greater than. -exec [cmd] {} \; invokes ls -l command on each file and awk strips off the values of the 5th (size) and the 9th (filename) column from the ls -l output to display. Sort is done in reversed order (descending) numerically using sort -rn options. A cron job could be run to execute a script like this and alert the users if a dir has files exceeding certain size, and provide file details as well.

Read almost everything (Changelog.gz, .tgz, .deb, .png, .pdf, etc, etc....)
It allows customizing by means of lesspipe. You need to write a ~/.lessfilter script and put this into your ~/.bashrc: eval $(lesspipe) export LESS=-r

Graphically show percent of mount space used
Automatically drops mount points that have non-numeric sizes (e.g. /proc). Tested in bash on Linux and AIX.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
