The large context number (-C 1000) is a bit of a hack, but in most of my use cases, it makes sure I'll see the whole log output.

I needed to get a feel for how "old" different websites were, based on their directories.

Discover host and url of media files (ex. flv, mp4, m4v..).

It locate the urls of audio and video files so that they can be recorded.

If you don't have seq, you can use perl.

Set field separator char from command line.

Prints first, second and lsat columns.

Have you ever wondered what the hell was dd command doing? well, there you have it... notice the -USR1 signal :)...

sudo when you mean it

ps aux | grep $USER

exit

# newline to space; the whack before dollar-underbar is required

alias nl2space="perl -ne 'push @F, \$_; END { chomp @F; print join(qq{ }, @F) , qq{\n};}' "

# newline to comma; the whack before dollar-underbar is required

alias nl2,="perl -ne 'push @F, \$_; END { chomp @F; print join(qq{,}, @F) , qq{\n};}' "

# 'tr' does not take arguements

tr: extra operand `/tmp/foo'

Try `tr --help' for more information.

# 'nl2space' is a filter and takes arguements, adds a newline after it runs.

xargs deals badly with special characters (such as space, ' and "). To see the problem try this:

touch important_file

touch 'not important_file'

ls not* | xargs rm

Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.

-l for long list, -r for recursive, -a for display of hidden files, and -t for modification date

Get information pci All

do it, disown it and exit without time for a mess

sudo when you mean it

ps aux | grep $USER

exit

The command will help to print the location of the pattern. Above command will print all the files which contain variable "$foo" along with line containing that pattern.

Specify pattern after "grep"

All folders, human-readable, no subfolder, with a total. Even shorter.
