On-the-fly conversion of Unix Time to human-readable in Squid's access.log
Another version based on linkinpark342's contribution.
Sometimes you have to browse your way through a lot of sub-directories. This command cd to the next sub-directory in alphabetical order. For example, if you have the directories "lectures/01-intro", "lectures/02-basic", "lectures/03-advanced" and so on, and your PWD is "02-basic", it jumps to "03-advanced".
Create a tgz archive of all the files containing local changes relative to a subversion repository.
Add the '-q' option to only include files under version control:
$svn st -q | cut -c 8- | sed 's/^/\"/;s/$/\"/' | xargs tar -czvf ../backup.tgz
Useful if you are not able to commit yet but want to create a quick backup of your work. Of course if you find yourself needing this it's probably a sign you should be using a branch, patches or distributed version control (git, mercurial, etc..)
You can specify various output formats, theme styles, etc.
$ python -m pygments -o source.png source.py
$ python -m pygments -o source.rtf source.py
Check available output formats, styles, etc.:
$ python -m pygments -L
Find pygments module here: http://pygments.org/
This will output the characters at 10 per second.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
Imagine you've started a long-running process that involves piping data,
but you forgot to add the progress-bar option to a command.
e.g.
$ xz -dc bigdata.xz | complicated-processing-program > summary
.
This command uses lsof to see how much data xz has read from the file.
$ lsof -o0 -o -Fo FILENAME
Display offsets (-o), in decimal (-o0), in parseable form (-Fo)
This will output something like:
.
p12607
f3
o0t45187072
.
Process id (p), File Descriptor (f), Offset (o)
.
We stat the file to get its size
$ stat -c %s FILENAME
.
Then we plug the values into awk.
Split the line at the letter t: -Ft
Define a variable for the file's size: -s=$(stat...)
Only work on the offset line: /^o/
.
Note this command was tested using the Linux version of lsof.
Because it uses lsof's batch option (-F) it may be portable.

Thanks to @unhammer for the brilliant idea.
Put this command in .bashrc and every time you open a new terminal a random quote will be downloaded and printed from onelinerz.net.
