Convert filenames from ISO-8859-1 to UTF-8

Warn: use convmv or detox if you can: they are the right tools. But if you want to do it manually, you can use this command to find the problematic files and transliterate their accented characters to their ascii equivalent. (Useful when doing cd backup: growisofs may fail on files which come from the old iso8859-* days.)

Propagate a directory to another and create symlink to content

Lndir create from source directory to destination directory a full symlink tree of all contents of source directory, really useful for propagate changes from a directory to another.

Replace spaces in filenames with underscores

It's the rename-tool from debians perl-package.

Speed up launch of liferea

If you use liferea frequently, you will see obvious speedup after you executed this command.

Short Information about loaded kernel modules

I modify 4077 and marssi commandline to simplify it and skip an error when parsing the first line of lsmod (4077). Also, it's more concise and small now. I skip using xargs ( not required here ). This is only for GNU sed. For thoses without GNU sed, use that : $ modinfo $(lsmod | awk 'NR>1 {print $1}') | sed -e '/^dep/s/$/\n/g' -e '/^file/b' -e '/^desc/b' -e '/^dep/b' -e d

Recompress all text files in a subdirectory with lzma

This will deal nicely with filenames containing newlines and will run one lzma process per CPU core. It requires GNU Parallel http://www.youtube.com/watch?v=OpaiGYxkSuQ

check open ports without netstat or lsof

Binary digits Matrix effect

Silly Perl variant.

Save a file you edited in vim without the needed permissions

Calls sudo tee like all the other lines, but also automatically reloads the file. Optionally you can add command Wq :execute ':W' | :q and command WQ :Wq to make quitting easier

For finding out if something is listening on a port and if so what the daemon is.
