gawk is a pattern scanning and processing language.
By default it reads standard input and writes standard output.

Examples:
    gawk '{ sum += $1 }; END { print sum }' file
    gawk -F: '{ print $1 }' /etc/passwd
./awktest.sh: line 4: BEGIN { 
    print "line one\nline two\nline three" 
}: command not found

Hi.

Not this...

awk 
'BEGIN { 
    print "line one\nline two\nline three" 
}'

But this...

awk '
  BEGIN { 
    print "line one\nline two\nline three" 
}'

or this...

awk \
'BEGIN { 
    print "line one\nline two\nline three" 
}'

Thank you.
But this is not working:

awk \ 
'BEGIN { 
	print "line one\nline two\nline three" 
}'

./awktest.sh: line 4: BEGIN { 
	print "line one\nline two\nline three" 
}: command not found

Post the content of your script between code tags.

}'

Hi.

It should work.. it works for me!

Use the other one instead then

Your script should looks like:

#!/bin/sh

awk 'BEGIN { 
    print "line one\nline two\nline three" 
}'

This should work too:

#!/bin/sh

awk \
'BEGIN { 
	print "line one\nline two\nline three" 
}'

Regards

I got the problem.It's the extra space after the "\" character.
If I copy and paste this it works.

awk \
'BEGIN { 
    print "line one\nline two\nline three" 
}'

But if I copy and paste this it doesn't work.(copy and paste the below one you will get error).Extra space after "\" character.

awk \ 
'BEGIN { 
    print "line one\nline two\nline three" 
}'
