Hi gianvitolinuxs,
Welcome to the UNIX & Linux Forums.
Is this a homework assignment? Homework and coursework questions can only be posted in
the Homework and Coursework Questions forum under
special homework rules.
Please review the
rules, which you agreed to when you registered, if you have not already done so.
If you did post homework in the main forums, please review the
guidelines for posting homework and repost.
If you did not post homework, please explain the company you work for and the nature of the problem you are working on and give us a lot more information so we can figure out how to help you.
- What variable do you want to set? In what language will this variable be used? (Such as a Bourne shell compatible shell, a csh compatible shell, awk, perl, C, etc.)
- Which Linux operating system are you using?
- What shell are you using?
- Is the value to be assigned to your variable the constant 9d424312 you specified in post #1? If not, how is your script supposed to determine that it has found the value that you want to assign to your variable from your file?
- What is the name of your file? In what directory will that file be found?
- What have you tried to solve this problem on your own?

SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-a] [-c COMMAND] [-f] [-q] [-t] [file]
DESCRIPTION
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Options:
-a Append the output to file or typescript, retaining the prior contents.
-c COMMAND
Run the COMMAND rather than an interactive shell. This makes it easy for a script to capture the output of a program that behaves
differently when its stdout is not a tty.
-f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super-
vise real-time what is being done using `cat foo'.
-q Be quiet.
-t Output timing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time
elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used
to replay typescripts with realistic typing and output delays.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. Script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO
csh(1) (for the history mechanism), scriptreplay(1).
HISTORY
The script command appeared in 3.0BSD.
BUGS
Script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
AVAILABILITY
The script command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
