Facilite la navigation entre des répertoires qui ont la même structure.
Prenons pour exemple l'architecture de dossiers suivante

   +- data
     +- winA052
     | +- prod
     | | +- soft1
     | | | +- V12
     | | +- soft3
     | |   +- V3
     | |   +- V4
     | +- test
     |   +- soft1
     |     +- V13
     +- winA061
     | +- prod
     | | +- soft2
     | |   +- V1
     | +- test
     |   +- soft2
     |     +- V2
     +- winX051
     | +- prod
     |   +-soft1
     |     +-V12
     +- rheA060
       +- prod
       | +- soft2
       |   +- V1
       +- test
         +- soft2
           +- V2

Pour naviguer de /data/winA052/prod/soft1 vers /data/winA052/test/soft1 la commande cd ../../test/soft1 ici est remplacée par l'alias test.

alias test='
dir=`pwd | sed "s#/prod#/test#"`;
if [ -d "$dir" ];
then
  cd "$dir";
fi'

sed remplace prod par test dans le répertoire courant (pwd), si ce répertoire existe on fait un cd pour s'y rendre.

Petite explications sur la signification de ces codes:

• win → Windows
• rhe → Red Hat Enterprise Linux
• X → architecture x86 (32bit)
• A → architecture AMD64 (64bit)
• 051 → version de l'OS

winX051 correspond donc à Windows XP 32bit, winA052 Windows XP 64bit, winA061 Windows 7 64bit, rheA060 Red Hat Enterprise Linux v6.x

Si on veut passer de /data/winA061/prod/soft2/V1 vers /data/rheA060/prod/soft2/V1 l'alias rheA060 remplacera cd ../../../../rheA060/prod/soft2/V1.

alias rheA060='
pwd | grep -qe "win[AX][0-9]\{3\}" -e "rheA[0-9]\{3\}";
if [ $? -eq 0 ];
then
  dir=`pwd | sed "s|/win[AX][0-9]\{3\}|/rheA060|; s|/rheA[0-9]\{3\}|/rheA060|"`;
  if [ -d "$dir" ];
  then
    cd "$dir";
  fi;
else
  cd /data/rheA060/prod;
fi'

on recherche les différentes architectures winX051; winA052, …
si on trouve quelque chose on remplace l'architecture par rheA060
si le répertoire existe on s'y rend
si on a rien trouvé au premier test on se rend directement dans /data/rheA060/prod.
