Awk replacement problem
Hello everyone,
I have a problem with awk replacement... I need to replace "|\n" for "\n"
I tried this
Code:
awk '{ sub(/\|\\n/, "\\n"); print }'

but it seems like it doesn't work properly. Can anyone help with that?

Does it have to be AWK?
Code:
perl -pe 's/\|\\n/\\n/' file

Your first attempt works if "\n" is a literal string within your file:
Code:
$ cat test1
one two|\nmore
another line
done|\n
$ awk '{ sub(/\|\\n/, "\\n"); print }' test1
one two\nmore
another line
done\n

But I think you probably want to remove a pipe character from the end of any line (correct?):
Code:
$ cat testfile
one two three|
no pipe
done|
$ awk '{ sub(/\|$/, ""); print }' testfile
one two three
no pipe
done
