I've got one I haven't been able to figure out.
1. A shell script exists- /junk/junk1/junk2/junk3.sh
2. From within the above named shell script, I want to know the full path of the above named shell script. Even if I execute the shell script from a directory other than the one it resides in, I want to know the directory where the script resides, not the path where the script was executed from.
For example:
I'm in: /home/myhome
and I put the following on the command line: /junk/junk1/junk2/junk3.sh
I want the following stored to a variable inside the script: /junk/junk1/junk2
I don't want the following stored to a variable inside the script: /home/myhome
How do I figure this out?
TIA
Paul

Hi,
I have a file with about 60 lines of path:
app-defaults/boxXYZ.......
I want to change this to /my/path/goes/here/app-defaults/boxXYZ, but of course vi doesn't like the regualr :s/old/new/ command.
Is there any other quick way to do this?
Thanks ;) (2 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

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.
