-bash_completion is a better solution. bash_completion seems to be widely available on g5k nodes. You just have to add these lines in your .bashrc, and then try oarsh <TAB>
 <code bash>

 ===== PROMPT BASH for Interactive jobs =====
 If you want to have a bash prompt with your job id and the remaining walltime then you can add in your ~/.bashrc:
 <code bash>
-  if ["$PS1" ]; then
+if [ "$PS1" ]; then
-      __oar_ps1_remaining_time(){
+    __oar_ps1_remaining_time(){

-              DATE_NOW=$(date +%s)
+            DATE_NOW=$(date +%s)
-              DATE_JOB_START=$(stat -c %Y $OAR_NODE_FILE)
+            DATE_JOB_START=$(stat -c %Y $OAR_NODE_FILE)
-              DATE_TMP=$OAR_JOB_WALLTIME_SECONDS
+            DATE_TMP=$OAR_JOB_WALLTIME_SECONDS
-              ((DATE_TMP = (DATE_TMP - DATE_NOW + DATE_JOB_START) / 60))
+            ((DATE_TMP = (DATE_TMP - DATE_NOW + DATE_JOB_START) / 60))
-              echo -n "$DATE_TMP"
+            echo -n "$DATE_TMP"
-          fi
+        fi
-      }

-      if [-n "$OAR_NODE_FILE" ]
