@ctsgnb: It does work for file t1 in post #8. And you might also want to take a look at this. May be the awk installed on my system is having a hangover ;-)

Code:
[root@host dir]# cat file
alpha 200 this is a comment for this record
bravo 400 this is another comment for this record
[root@host dir]#
[root@host dir]# awk 'sub(".*"$3,$1RS$2RS$3)' file
alpha
200
this record
bravo
400
this record
[root@host dir]#

Instead of "this is a comment for this record", it just prints "this record". I'm using GNU Awk 3.1.5

awk treating variables differently in UNIX-Linux

Hi, awk seem to be acting differently in Unix and Linux when it comes to formatting. This is making it difficult to migrate scripts. for example: UNIX: echo "123" |awk '{printf ("%05s\n" ,$1)}' 00123 echo "123" |awk '{printf ("%05d\n" ,$1)}' 00123 echo "S12" |awk '{printf ("%05s\n"... (9 Replies)

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.10 30 Jan 2004 script(1)
