I think he means that in the line:
UPDATES_NEEDED=`cat $LOG | grep "updates detected" | tail -1`
cat $LOG... will hang if $LOG == "" because "cat" is waiting for input.
Precisely.
That helps but my problem is the line above where it get the value for
LOG for whatever reason doesn't get the value of LOG in the for loop
but can outside of the loop... :o)
You mean this line?
LOG=`ls -al $DIR | grep $t | grep WINDOWS`
You're listing the contents of the directory, trying to find the one line
that contains the name of the file ($t) you're currently considering. Then
you're using grep a second time to only select (from that one line) any lines
that contain the text 'WINDOWS'. Presumably none of the files in
1group_1a_dev_clientlist.out have the word "WINDOWS" in their name.
What are you *trying* to do with that second grep?
cheers,
DaveK
There are 2 files related to each client listed in the file
1group_1a_dev_clientlist.out the first grep grabs both files and the
second one get the specific log with the work windows in it:
[EMAIL PROTECTED] /cygdrive/e/wsus/group_1a_DEV
$ ls -al

for t in `cat $DIR/1group_1a_dev_clientlist.out`
do
echo $t
#LOG=`ls -al $FILE | grep $T | grep WINDOWS | gawk '{print $9}'`
#LOG=`ls -al cygdrive/e/wsus/group_1a_DEV | grep $t | grep WINDOWS |
gawk '{print $9}'`
LOG=`ls -al $DIR | grep $t | grep WINDOWS`
echo $t
echo The value of LOG is $LOG
UPDATES_NEEDED=`cat $LOG | grep "updates detected" | tail -1`
echo $UPDATES_NEEDED
done
Thanks!
