'''ps'''

Use a pipe grep  (`|grep`) to select users or processes names.

Useful options :

 * a : all processes, not only current user's process
 * u : sorted by user
 * f : show arborescence

exemple ci-dessous : `ps fau | grep matlab`

'''List process with a given processname''' (list of PID numbers): `ps -u 'username' | grep processname` (`|grep` detects a string in any display)

== kill process ==
{{{
kill 'number PID' or stronger  'kill -9 'numero PID' 
}}}
(case of thunderbird: need also to suppress lock files, use command 'rmLock')

== Synchronisation of files ==
{{{
rsync -a rep1 rep2/   
}}}
(be careful with /  , synchronise the directory "rep1" with rep1 existing in rep2 ;)

== Change file access properties ==
 * examples (can be performed only by the file owner):

 * change all png files to read-only in the current directory:
{{{
 chmod ugo-w *.png
}}}

 * provide writing access for your group to a directory dirname (or to a file):
{{{
chmod ugo+ws dirname
}}}

== Monitor disk space ==
{{{
 df -a
}}}
gives all the partitions and their status

{{{
 du --max-depth=2 -h
}}}
browse recursively a folder, and gives the space of each block

example :

{{{
 gostiaux@eres0vmbig2:/fsnet/project/coriolis/2011$ du --max-depth=1 -h
 0       ./lost+found
 556G    ./11KUROSHIOMANI
 337G    ./11BORDES
 625G    ./11TRANSTEK
 1,5T 
}}}
== Monitor users ==
List potentially connected users

{{{
 ps faux | cut -f 1 -d ' ' | sort | uniq
}}}

== loading the source of uvmat as zip file on the web server ==
 1. Open a terminal and go to servcalcul3 by ssh (not on bigtwo).
 2. Get an updated version from the svn server by typing:
{{{
svn checkout http://servforge.legi.grenoble-inp.fr/svn/soft-uvmat/trunk/src uvmat
}}}
 3. compress the folder uvmat as a zip archive, name it as uvmat.v....zip with ... =version number
 4. transfer the archive to the web site using cadaver (like FTP). 
{{{
cadaver https://servforge.legi.grenoble-inp.fr/pub/soft-uvmat/ 
put uvmat.v....zip
rm older version
exit
}}}
