Shell Programming and Scripting

hi,

I have a baby.txt file with two type of message:

xxxxxxxx is missing
xxxxxxxxxxx is not missing
xxxx is missing
xxxxxxxx is not missing
xxxxxxxx is not missing

For the above, I need to read file and get all "xxxx is missing" and write into baby_missing.txt. If no message "xxxxx is missing" in whole baby.txt, the script will write message "no file is missing in system" to baby_nomissing.txt

is it possible? if yes..how?

Code:

awk ' /is missing/ { flag=1;print > "baby_missing.txt" }
END { 
if( flag != 1 ) 
    print "no file is missing in system" > "baby_nomissing.txt" 
} ' baby.txt

the script display the following error:
ksh: syntax error: `}' unexpected

Its working for me.Check whether you have missed brace in your script

May be I added mailx into.. can you help?

awk ' /is missing/ { flag=1;print > "baby_missing.txt" }
mailx -c "`cat ccfile.txt`" -s \'"Missing tap file status $today'" "`cat tofile.txt`" < missing.msg
END {
if( flag != 1 )
print "no file is missing in system" > "baby_nomissing.txt"
} ' baby.txt

You have to use system() function to execute unix commands within awk.

what do you mean? I changed {} to () ....but still not work.
