!! Replace literal "\n" and "\t" in a file with newlines and tabs
cat $file | perl -ne 's/\\n/\012/g; s/\\t/\011/g; print'
+(This has a useless use of "cat", and uses perl -n (for no print) and then does an explicit print.) This could be rewritten as:
+ perl -pe 's@\\n@\012@g; s@\\t@\011@g' < $file
+(you can use any punctuation as the separator in an s/// command, and if you have \ chars in your regexp then doing this can increase clarity.)
