Exiting from the script abruptly
Hi Team,

Need your help for the below code snippet. I wrote a module to read the file names remote server using file name convention.

Issue : My script is coming out from while loop without reading complete file.

HTML Code:
 test1()
{
while read line
do
echo $line
file_nm_convention=`echo $line | awk -F${CFG_DELIMETER} '{print $1}'`
uid=`echo $line | awk -F${CFG_DELIMETER} '{print $2}'`
svr=`echo $line | awk -F${CFG_DELIMETER} '{print $3}'`
dir=`echo $line | awk -F${CFG_DELIMETER} '{print $4}'`
ssh  $uid@$svr "cd $dir;ls -lrt $file_nm_convention"  1>${LST_FILE_NM}
cat $LST_FILE_NM 
done  < ${CFG_FILE}
exit
}
cat cfg_file
test*.ack|kittuad|svr_abc|/home/kittuad
s_test*.ack|kittuad|svr_abc|/home/kittuad

I am getting output only for test*.ack but not for s_test*.ack

How about:
Code:
CF=cfg_file

cat > $CF << EOF
test*.ack|kittuad|svr_abc|/home/kittuad
s_test*.ack|kittuad|svr_abc|/home/kittuad
EOF


oIFS="$IFS"
IFS="|"
while read file user svr home;do
	printf '%s\n' \
		"" \
		"File: $file" \
		"User: $user" \
		"SVR: $svr" \
		"Home: $home"
	ssh $user@$svr << EOF
echo "Tasks on the remote"
cd $home
ls $file
EOF

done<$CF
IFS="$oIFS""

Produces this for me: (added the ssh line later)
Code:
File: test*.ack
User: kittuad
SVR: svr_abc
Home: /home/kittuad

File: s_test*.ack
User: kittuad
SVR: svr_abc
Home: /home/kittuad

Hope this helps

EDIT:
Dont know where LST_FILE_NM is, but its not really required... unless you do another access somewhen later.
But since you just cat the regular ls output, you can loose cat

thanks for your reply. I got the solution

made below changes to the code and it is working

Code:
 test1()
{
while read line
do
echo $line
file_nm_convention=`echo $line | awk -F${CFG_DELIMETER} '{print $1}'`
uid=`echo $line | awk -F${CFG_DELIMETER} '{print $2}'`
svr=`echo $line | awk -F${CFG_DELIMETER} '{print $3}'`
dir=`echo $line | awk -F${CFG_DELIMETER} '{print $4}'`
ssh  $uid@$svr "cd $dir;ls -lrt $file_nm_convention"  1>${LST_FILE_NM} </dev/null
cat $LST_FILE_NM 
done  < ${CFG_FILE}
exit
}

Yes ssh was eating your standard input redirect from /dev/null will fix it for you.

It's worth looking at sea's solution as there are some nice techniques for extracting the uid, svr, etc without spawning 3 sub-shells and 3 awks.
