Out of curiosity, I also tried some testing myself. On a file with 250 lines there's no difference.
But on a file with 1000 lines, cut was faster by 1 sec.
On a file with 10000 lines, the result is the same:
I'm using HP-UX. Maybe awk is better for files far larger than 10000 lines while cut is better for smaller files. Or maybe because of their differences in primary use. I'm not sure about this though. Need to do some more tests.

After my big disaster, I'm restoring from tape on my Sun box. This is the second time I've used 'ufsrestore' with this DEC TZ88 SCSI DLT drive. The last time was for a migration from one box to another. Both the last time and this time, the restore has taken a hell of a lot longer than the... (4 Replies)
Hi, I'm very new to scripting.
grep $s $filename | awk '{print $2}' | cut -c 1-8
How can I optimize this using a single awk?
I tried:
awk '/$s/ {print $2}' $filename | cut -c 1-8
However didn't work, I think the awk is not recognizing $s and the verbal is something else. (6 Replies)

Hi All,
We run Many jobs evryday using Autosys. Sometimes due to various reason we got to run the job from terminal as well (using nohup).
We observed that the job running through terminal(nohup) takes much less time then the autosys (for same job).
What can be the possible reason for such... (1 Reply)

linsert
linsert(3tcl) Tcl Built-In Commands linsert(3tcl)__________________________________________________________________________________________________________________________________________________NAME
linsert - Insert elements into a list
SYNOPSIS
linsert list index element ?element element ...?
_________________________________________________________________DESCRIPTION
This command produces a new list from list by inserting all of the element arguments just before the index'th element of list. Each ele-
ment argument will become a separate element of the new list. If index is less than or equal to zero, then the new elements are inserted
at the beginning of the list. The interpretation of the index value is the same as for the command string index, supporting simple index |
arithmetic and indices relative to the end of the list.
EXAMPLE
Putting some values into a list, first indexing from the start and then indexing from the end, and then chaining them together:
set oldList {the fox jumps over the dog}
set midList [linsert $oldList 1 quick]
set newList [linsert $midList end-1 lazy]
# The old lists still exist though...
set newerList [linsert [linsert $oldList end-1 quick] 1 lazy]
