Print out contents of file with line numbers.

This version will print a number for every line, and separates the numbering from the line with a tab.

if you have a alias like this:

alias cp='cp -i'

# cp file1 file1.bak

equal to

# cp -i file1 file1.bak

(it will not overwrite file1.bak if it exist)

# \cp file1 file1.bak

equal to

# /bin/cp file1 file1.bak

(skip alias settings, it will overwrite file1.bak if it exist)

d --> delete

!d ---> delete others

The quality ranges between 0 to 9, with the smaller number indicates a higher quality file but bigger too.

Next time you see a mac fanboy bragging about 64-bitness of 10.6 give him this so he might sh?

Used it on daily basis, not sure if it's any better than the OPs version, tho'

One advantage is - you can replace 'bash' at the end of the line with eg. cat - to check if the generated command is OK.

Perl version - just for completeness sake ;)

Uses Unicode combining characters to produce strikethrough effect. Since commandlinefu doesn't display Unicode properly, you will need to replace the dash in the code above with the Unicode long stroke overlay (U+0336).

rsync by itself doesn't support copying between two remote hosts, but if you use sshfs you can pretend one of them is local. If you have a passphrase-less ssh-key, you can even put this script into a cron job.

A faster alternative is to run ssh-keygen on remote1 and put the pubkey into remote2:~/.ssh/authorized_keys, running rsync on remote1 (or vice versa), but the problem with that is that now a hacker on remote1 can access remote2 at any time. The above method ensures your local computer stays the weak link.

Git uses secure hash sums for its revision numbers. I'm sure this is fine and dandy for ultra-secure computing, but it's less than optimal for humans. Thus, this will give you sequential revision numbers in Git all the way from the first commit.

Per country GET report, based on access log. Easy to transform to unique IP

You cannot kill zombies, as they are already dead. But if you have too many zombies then kill parent process or restart service.

You can kill zombie process using PID obtained from the above command. For example kill zombie proces having PID 4104:

# kill -9 4104

Please note that kill -9 does not guarantee to kill a zombie process.

This alternative cleans HISTTIMEFORMAT environment variable and calls gnuplot just after /tmp/cmds is closed, to avoid some errors.

For debian likes, that's in python-xml package.

This is a function that implements an improved version of tail. It tries to limit the number of lines so that the screen is filled completely. It works with pipes, single and multiple files. If you add different options to tail, they will overwrite the settings from the function.

It doesn't work very well when too many files (with wrapped lines) are specified.

Its optimised for my three-line prompt.

It also works for head. Just s/tail/head/g

Don't set 'thbin="tail"', this might lead to a forkbomb.

Where "docname" is the document you want OS-X to image... file.txt, file.pdf, file.mov, etc

Use one CPU core entirely.

Change lang from ru to something else.

Curl version - Mac OS etc, any system w/o wget.

needs no GNU tools, as far as I see it

why would you want to convert mp3's to ogg? 1 reason is because ardour doesn't support mp3 files because of legal issues. this is really the only reason you would do this, unless you have really bad hearing and also want smaller file sizes, because converting from one lossy format to another isn't a good idea.
