Nested Do statements 2

[coopermarsh]

Hi Gurus

I am trying to automate a whole process using a script

is it possile to nest do statements

thanks for looking


my script is

for FILE in `ls *.txt`;
do
FILEN=$FILE | sed 's/.txt//'
for VOL in `cat $FILE`;
do 

/opt/tivoli/tsm/client/ba/bin/dsmadmc -se=server -id=######## -password=${PASS} "select volume_name from volumes where volume_name='$VOL'" >> /tmp/cont/${FILEN}_bfs.txt ;
done
done

Yes you can e.g.
for i in 10 20
do
for j in 1 2
do
echo $i $j
done
done
10 1
10 2
20 1
20 2

Hi

If you are getting all your output in a single file, /tmp/cont/_bfs.txt, then start debugging with this line :

FILEN=$FILE | sed 's/.txt//'

You are piping a variable assignment

[tt]FILEN=$FILE[/tt]

which doesn't generate any output by the way into a sed process. That won't work...

I suspect you want FILEN to contain the filename in variable FILE but without the .txt

This last step can be done with sed, but you also need command substitution.

to generate the filename with sed:

[tt]echo ${FILE}|sed 's/.txt//'[/tt]

another option is to use the basename command

[tt]basename ${FILE} ".txt"[/tt]


now to put the output of a [tt][red]command[/red][/tt] into a variable, use command substitution:

var=`[tt][red]command[/red][/tt]`

or

var=$([tt][red]command[/red][/tt])

Now it's up to you to put two and two together an see where it gets you.


HTH,

I think you wanted something like this:

for FILE in `ls *.txt`; do
  FILEN=`basename $FILE .txt`
  for VOL in `cat $FILE`; do
    /opt/tivoli/tsm/client/ba/bin/dsmadmc -se=server -id=######## -password=${PASS} "select volume_name from volumes where volume_name='$VOL'" >> /tmp/cont/${FILEN}_bfs.txt
  done
done

Hope This Helps, PH.
