All commands

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.

(Please see sample output for usage)

Use any script name (the read command gets it) and it will be encrypted with the extension .crypt, i.e.:

myscript --> myscript.crypt

You can execute myscript.crypt only if you know the password. If you die, your script dies with you.

If you modify the startup line, be careful with the offset calculation of the crypted block (the XX string).

Not difficult to make script editable (an offset-dd piped to a gpg -d piped to a vim - piped to a gpg -c directed to script.new ), but not enough space to do it on a one liner.

Sorry for the chmod on parentheses, I dont like "-" at the end.

Thanks flatcap for the subshell abbreviation to /dev/null

'readlink -fn' gets canonical path of the file/directory without newline at the end;

'xsel -ib' copies pipelined string from STDIO to system clipboard (ready to be pasted with CTRL+V).

Execute matlab sentences in shell script:

for var in `seq 0 0.2 1` ; do

echo "my_function($var);" | matlab -nodisplay

done

(Please see sample output for usage)

script.bash is your script, which will be crypted to script.secure

script.bash --> script.secure

You can execute script.secure only if you know the password. If you die, your script dies with you.

If you modify the startup line, be careful with the offset calculation of the crypted block (the XX string).

Long listing alternative

make a bunch of files with the same permissions, owner, group, and content as a template file

(handy if you have much to do w. .php, .html files or alike)

Get the amount of physical memory in an HP-UX v11 OS when following are NOT available:

- root account

- no privileges in /proc

- no privileges in /dev/mem

instead of printing the whole line, print just the capture matched, but with the "cut" pipe :( I'm so sad with grep.

In order to unrar several files in different subfolders, you just need to launch this command in your parent folder in order to have your files ready for manipulation and already extracted;

I did not put anything to delete the original rar files

Very similar as doing "wget http://example.com/mytarball|tar xzv", this one involves the "tee" command between both, which will simultaneously write the tarball and copy it to stdout. So this command will locally save the tarball and extract it - both at the same time while it downloads.
