Very nice, works well. Can you do me a huge favor and break down the sed command you used here and why it works the way it does... I am still trying to figure out how to properly use it and I learn by examples better than reading hypothetical explanations.
I set my path environment variable in c shell, using the
syntax below
setenv PATH "${PATH}:/usr/local:/usr/local/bin"
and placed this in $HOME/.login
$HOME/.cshrc
and /etc/.login
/etc/.cshrc
but when I issued echo $PATH or set command
the output does not reflect changes made to... (5 Replies)

I want to add "/opt/SUNWspro/bin" to the search path for all the users. Where can I access this variable.

For some reason something has changing in my AIX environment where when I type:
ACLEDIT filename
...I get:
3002-104 acledit: EDITOR environment variable must be full pathname
I know I need to reset the EDITOR variables path to /usr/bin/vi but I can't remember the syntax anyone? (2 Replies)
I've noted that in order to use commands like ifconfig, I have to prefix the commands with the directory.
/etc/profile shows that the paths should be part of the PATH environment variable; any idea where the bug is?

Hi I'm trying to select text between two lines, I'm using sed to to this, but I need to pass variables to it. For example
start="BEGIN /home/mavkoup/data"

sed -n -e '/${start}/,/${end}/g' doesn't work. I've tried double quotes as well. I think there's a problem with the / in the... (4 Replies)

Below is my script I am looking to add this feature too.

Hi Folks -
I was wondering if you could help convert batch code in Linux? For instance, I use the following piece of code in DOS to find a file/executable, and then the FULL path as a variable.
::-- If startMaxl.exe exists, set full path --::

shell-quote
SHELL-QUOTE(1p) User Contributed Perl Documentation SHELL-QUOTE(1p)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
