Shell Programming and Scripting

Anyone who can assist :

I am trying to pass the group vairiable to a filename:
rpt_tsavegrp=/export/legato/scripts/$group_savegrp_rpt.$dat

It will not pass to variable.
Anyone have any ideas what I am doing wrong here.
Thanks



# This script sends email that save group completed.
#!/bin/ksh
dat=`date +%m%d%y`
rdat=`date +%m/%d/%y`
savegrp=/export/legato/scripts/savegrp_rpt.tmp
rpt_tsavegrp=/export/legato/scripts/$group_savegrp_rpt.$dat
cat $* > $savegrp
group=`head -1 $savegrp |grep -v -i media |awk '{print $4,$5}'`>/dev/null
#/usr/ucb/mail -s "$group Test Savegroup Report - $rdat" < $savegrp
#cp $savegrp $rtp_savegrp

What do you mean, "will not pass to variable"? What does happen? What do you want to happen?

Are both "$group_savegrp_rpt" and "$dat defined"?

Or do you mean:

Code:

rpt_tsavegrp=/export/legato/scripts/${group}_savegrp_rpt.$dat

Why make two identical calls to an external command?

Code:

rdat=$dat

Where is $group_savegrp_rpt defined?

That will fail if there are any spaces in the arguments. Use:

Code:

cat "$@" > "$savegrp"

What are you sending to /dev/null? If it's outside the backticks, you are doing nothing, since an assignment doesn't produce any output. If it's inside, there will be nothing assign to the variable.

It's not clear what you are trying to do here. Whatever it is, you can almost certainly do it without calling three external commands; in fact, probably without any:

Code:

read a b c d e f < "$savegrp"
case "$a $b $c $d $e $f" in ## adjust to where 'media' might appear
  *media*) group="$d $e" ;;
esac

For some reason, my $group vairable will not pass to the $savgrp_rpt.
Still doesn't work.

# This script sends email that save group completed.
#!/bin/ksh
dat=`date +%m%d%y`
rdat=`date +%m/%d/%y`
tmp_savegrp=/export/legato/rpts/savegrp.tmp
cat $@ > $tmp_savegrp
group=`head -1 $tmp_savegrp |grep -v -i media |awk '{print $4,$5,$10}'
/usr/ucb/mail -s "$group Savegroup Report - $rdat" xxxx@xxx.com < $tmp_savegrp
savgrp_rpt=/export/legato/rpts/${group}_savegrp_rpt.$dat
cp $tmp_savegrp $savgrp_rpt
~

Where did you define $group?

If it is in a parent process, did you export it?
