Remote Shell Execution Problem
in [Shell]

From: invincible on 21 Apr 2008 11:53 All, Im trying to execute some commands on remote server thorugh script and ssh. When I run a normal command from prompt I do not get any error messages but when I run it thorugh script I get the execute permission denied message. Script is as below #Checking the presence of tasks file USR=abcd@ LISTSERVER="dubba libba" OUTFILE=/home//testing/scriptoutput #Create new file >$OUTFILE #Connect each server and pull up the listing for host in $LISTSERVER do echo "------------------------------------------------" >>$OUTFILE echo " * HOST : $host " >>$OUTFILE ssh $USR$host "more /home/apps/conf/tasks.tbl|awk '{print \$1}'" >>OUTFILE done The error enounterd is ... ../check_ps /home/apps/conf/tasks.tbl: The file access permissions do not allow the specified action. I can although run the command ssh USR$host "more /home/apps/conf/tasks.tbl|awk '{print \$1}'" on the command prompt and get the desired result. Hoping for some inputs.... __.____._

Also, what's the point of piping the output of "more" to awk, rather than the file directly? These probably won't solve your problem, but are worth correcting. -- All the commands are tested with bash and GNU tools, so they may use nonstandard features. I try to mention when something is nonstandard (if I'm aware of that), but I may miss something. Corrections are welcome.

[...] > ssh $USR$host "more /home/apps/conf/tasks.tbl|awk '{print \$1}'" Try replacing that with ssh $USR$host env and see if it's different between your command line and the script. -- Glenn Jackman "If there is anything the nonconformist hates worse than a conformist, it's another nonconformist who doesn't conform to the prevailing standard of nonconformity." -- Bill Vaughan

Thanx all, the problem has been solved out with the help of good memebers of this forum. It seems it was all the small problem you all had listed out which was creating the issue. |
