$SCRIPT_DIR/run_cmd_.sh 192.131.58.35 uname pass $line | grep -v "Enter command:" >> $REPORT_DIR/$file.TMP #$file.tmp will contail untrim and unjoined lines

#to trim and join the lines

open (FH,"<$REPORT_DIR/$file.TMP");
while(<FH>)
{
if (/\w+/)
{
print;
}
}
close (FH);

mv $REPORT_DIR/$file.TMP $REPORT_DIR/$file.LOG

By the way, what is "FH" here??

That Script what I told u is PERL script.and FH is file handler there.
if u want to use shell script then do

In shell script
#!/bin/sh

SCRIPT_DIR/run_cmd_.sh 192.131.58.35 uname pass $line | grep -v "Enter command:" >> REPORT_DIR/file.TMP
sed '/^\s*$/d' /home/rahul/jatin/REPORT_DIR/file.TMP > REPORT_DIR/file.LOG

I am really wondered why none of the below is not working for my file!!!!

It does not clear the empty lines & join.
grep -v ^$ filename

sed '/^\s*$/d' filename

if u copy file from windos try this command

dos2unix filename
grep -v ^$ filename
here is my output

Okay i think I found why its not working. I did dos2unix filename. But still no outcome. Later i check the file with VI. I found-

DELETE:MD:TM,432350214576013;^M
^M
RESP:940120105;^M
DELETE:MD:TM,432350415547447;^M
^M
RESP:940120105;^M
SET:NOK:TM,432350110811018:T22,0;
^M
RESP:11000999;^M

^M is creating problem !!! please make your suggestion

Code:

sed '/^\s*^M/d file

Press Ctrl-v followed by Ctrl-m to enter "^M".
