All commands

I tested this command on Ubuntu.

`pwd` returns the current path

`grep -o` prints each slash on new line

perl generates the paths sequence: './.', './../.', ...

`readlink` canonicalizes paths (it makes the things more transparent)

`xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR.

Shows files and processes of the command php

bash only - no grep, sed, awk, whatever - zero overhead

alternatively using ifconfig instead of "ip addr ..."

A=$(ifconfig eth0); A=${A##*inet addr:}; echo ${A%% *}

Use it as bash-script.

The first positional parameter specifies the fixed length of the numerical index.

Further params specify the files to manipulate.

or

For example, I write

in my `~/.bashrc`.

I find it useful, when cleaning up deleting unwanted files to make more space, to list in size order so I can delete the largest first.

Note that using "q" shows files with non-printing characters in name.

In this sample output (above), I found two copies of the same iso file both of which are immediate "delete candidates" for me.

Decrypt with:

It is the best way i found to send a mail from the console in my centos server.

In these command i use lynx to get the top trend topic of Mexico, if you replace Mexico with other country, you will get the #1 Trending topic

Replace "user/sbin/sshd" with the file you would like to check. If you are doing this due to intrusion, you obviously would want to check size, last modification date and md5 of the md5sum application itself. Also, note that "/var/lib/dpkg/info/*.md5sums" files might have been tampered with themselves. Neither to say, this is a useful command.

Full output in one single git command, no pipes nor other process invocations.

Will also work under cmd on Windows, with MSysGit, and can be aliased, simply add

[alias]

branch-rel = "for-each-ref --sort=-committerdate --format='%1B[32m%(committerdate:iso8601) %1B[34m%(committerdate:relative) %1B[0;m%(refname:short)' refs/heads/"

to your .gitconfig file.

Created to deal with an overzealous batch rename on our server that renamed all files to .jpg files.

use .ssh file to login the server

1.use puttygen command convert .ppk file to .ssh file

echo "ls" > script.bash;

This is my script, a simple 'ls'.

gpg -c script.bash;

Here I encrypt and passord-protect my script. This creates file script.bash.gpg.

cat script.bash.gpg | gpg -d --no-mdc-warning | bash

Here I open file script.bash.gpg, decrypt it and execute it.

The original command doesn't work for me - does something weird with sed (-r) and xargs (-i) with underscores all over...

This one works in OSX Lion. I haven't tested it anywhere else, but if you have bash, gpg and perl, it should work.
