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

 gostiaux@eres0vmbig2:/.fsnet/data/eres/coriolis-home/gostiaux$ 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).
2. 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
   

3. 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.
