my alias's do't work in for loop.....

[jdespres]

I'm having problem using my aliases within a a for loop...

Bash....

for server in `[ -f $* ] && cat $* || echo $*`
do
##### Generate the data.....
$server "/usr/openv/volmgr/bin/vmoprcmd -devmon ds -no_format" 2>/dev/null > /home/pubuntu/${server}_drivestatus.txt
$server "/usr/openv/volmgr/bin/vmoprcmd -devmon hs" 2>/dev/null > /home/pubuntu/${server}_hoststatus.txt

##### Now send out the data.....
echo " "
echo "########## ${server} ##########"
echo " "
/bin/sed '1,4d' /home/pubuntu/${server}_hoststatus.txt| grep -iv connection
echo " "
/usr/bin/awk '{print $6, $3, $7, $8, $10, $36}' /home/pubuntu/${server}_drivestatus.txt |awk '{ if (NF > 5) print}'| sort
echo " "

done

I can use my aliases within the script... but not in the for loop...

Any idea's

Thanks....

I don't see any alias.

But I would like to see codetags.

A nice, working example without specific clutter would be nice. What do you expect, what do you get?

Under some circumstances, the body of a [tt]for[/tt] loop can be a subprocess. Aliases are not inherited by subprocesses like exported variables are.

If you need to use an alias, define it again as the first command in the [tt]do/done[/tt] loop.

Ok..... I'm doing something different.....

The following aliases work ::--->

alias cscnb01='ssh -tXC jdespres@cscnb01'
alias cscnb02='ssh -tXC jdespres@cscnb02'
alias etsnb02='ssh -tXC jdespres@etsnb02'
alias etsis24='ssh -qtXC jdespres@etsnb02 "ssh -qtXC etsbk31 \"$@\""ssh -qtXC etsis24 \"$@\"""'
alias uphsnb01='ssh -tXC jdespres@faraday "ssh -t -X -C tukey \"$@\""ssh -t -X -C uphsnb01 \"$@\"""'

I converted them to functions ::--->

cscnb01  () { ssh -tXC jdespres@cscnb01 "$@"; }
cscnb02  () { ssh -tXC jdespres@cscnb02 "$@"; }
etsnb02  () { ssh -tXC jdespres@etsnb02 "$@"; }
cdcnb02  () { ssh -tXC root@cdcnb02 "$@";}
etsis24  () { ssh -tXC jdespres@etsnb02 "ssh -tXC etsbk31 \"$@\""ssh -tXC etsis24 \"$@\"""; }
uphsnb01 () { ssh -tXC jdespres@faraday "ssh -t -X -C tukey \"$@\""ssh -t -X -C uphsnb01 \"$@\"""; }

All the aliases work great....

The last two functions do not..

I'm trying to throw the functions at the following for loop ::--->

for server in `[ -f $* ] && cat $* || echo  $*`
do
##### Generate the data.....
${server} "/usr/openv/volmgr/bin/vmoprcmd -devmon ds -no_format" 2>/dev/null > /home/pubuntu/${server}_drivestatus.txt 
${server} "/usr/openv/volmgr/bin/vmoprcmd -devmon hs" 2>/dev/null > /home/pubuntu/${server}_hoststatus.txt 
##### Now send out the data.....
echo " "
echo "########## ${server} ##########"
echo " "
/bin/sed '1,4d' /home/pubuntu/${server}_hoststatus.txt| grep -iv connection
echo " "
/usr/bin/awk '{print $6, $3, $7, $8, $10, $36}' /home/pubuntu/${server}_drivestatus.txt |awk '{ if (NF > 5) print}'| sort
echo " "
done

command line ::--->

script_name (either one server name or a file with names)

Looks like I'm having a issue running the vmoprcmd command across 3 hops...

Basically I'm attempting to run a command on remote systems


Thanks...

Can I use the zsh shell ?
