awk - print new line

Shell Programming and Scripting
1

Hi!
Could you pls help me with my problem?
My task is to find the longest line in several files - that's not the problem
the problem is, I want command bellow to be stored in array, but one result per line:

set line = (`cat $file | awk '{print NR, length, $0, "\n"}' | grep "^[0-9]* $longest"`)

the output of command

foreach r ($line)
    echo "Output: $r"
end

is:

Output: 2
Output: 2
Output: 22
Output: 3
Output: 2
Output: aa

but it should look like this:
Output: 2 2 22
Output: 3 2 aa

(in other words - I need command set line..... to be an array of lines, not words)

thanks a lot

In a real scripting shell, you would set the field separator to a newline:

IFS='
'
line=( $( awk '{print NR, length, $0, "\n"}' "$file" | grep "^[0-9]* $longest" ) )

I don't see an equivalent in csh, but I only gave the man page a quick glance.

You just complicate your life :rolleyes:

awk '{max=(max>NF)?max:NF}END{print max}' *

for any file in current directory

I got the following error: Unmatched '. or when I modify it:

IFS='\
  '

IFS=
: Command not found.

danmero: well, but I need to print the whole line (not just its length) - and if there are more line with max length, print them all
