= CoriolisUnixCommand - UNIX Command =
== Basic operations ==
 * to list content of the current folder: 'ls'. 'ls -al' to get more information.
 * to change name: mv 'old' 'new'
 * to delete: rm 'filename'
 * to delete folder: rmdir  'foldername' (after removing its content by 'rm *')

Use 'Table' key to complement any input command.

== Moving among folders ==
`cd 'absolute folder name' or relative name inside the current folder'` To go up:

{{{
cd ..
}}}
To go home

{{{
cd ~
}}}
To go to your home on the LEGI computer server (can be reached also by the Window system like KDE or GNOME)

{{{
cd /.fsnet/data/legi/calcul9/home/'login name'
}}}
== Moving to the LEGI computer server servcalcul3 by ssh ==
{{{
ssh -CX servcalcul
}}}
(-CX to allow graphic display for instance with Matlab) To reach your computer home from servcalcul3:

{{{
/.fsnet/data/team-meige/coriolis-home/'login name'
}}}
== List running processes ==
'''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')

A process with visible window can be also stopped directly by typing 'xkill' in a terminal and pressing the mouse on the window.

== 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 ==
'''Quota for a group''::

  {{{
quota -s -g -A
}}}
   The relevant folders must be first activated by a command like {{{cd}}} or {{{ls}}}'''.




'''disk space used by folders'''

{{{
 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 on the web server (for development of uvmat) ==
 1. Open a terminal and go to servcalcul3 by ssh (not on bigtwo).
 1. Get an updated version of uvmat from the svn server by typing:
{{{
svn checkout http://servforge.legi.grenoble-inp.fr/svn/soft-uvmat/trunk/src UVMAT
}}}
 1. compress the folder UVMAT as a zip archive,
{{{
zip -r uvmat_toolbox.v'number'.zip UVMAT 
}}}

where  'number' is the 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_toolbox.v'number'.zip
}}}

remove older version by command rm .  type 'exit' to exit cadaver.  For updating the demo files, same procedure but taking the sources from /.fsnet/soft/team-meige/UVMAT/UVMAT_DEMO_SOURCES.
