Show one line summaries of all DEB packages installed on Ubuntu based on pattern search

I sometimes want to know what packages are installed on my Ubuntu system. I still haven't figured out how to use aptitude effectively, so this is the next best thing. This allows finding by name.

The grep '^ii' limits the display to only installed packages. If this is not specified, then it includes listing of non-installed packages as well.

Exclude grep from your grepped output of ps (alias included in description)

Surround the first letter of what you are grepping with square brackets and you won't have to spawn a second instance of grep -v. You could also use an alias like this (albeit with sed):

alias psgrep='ps aux | grep $(echo $1 | sed "s/^\(.\)/[\1]/g")'

edit files in current and subdir, remove all lines that containing certain string

checking files in current and sub directories, finding out the files containing "sampleString" and removing the containing lines from the file.

* Beware that The command will update the original file [no backup].

The command can be extended if play with 'find' command together,

e.g. it is possible to execute on certain type of files: *.xml, *.txt... (find -name "*.xml" | grep....)

if anybody knows a better solution on that, please drop a comment. thx.
