Hi all,

#!/bin/ksh
file_name=$1
old_templet=$2
new_templet=$3
# Loop through every file like this
for file in file_name
do
cat $file | sed "s/old_templet/new_templet/g" > $file.new

Hi guys, I use this function which was provided to me by someone at this site. It works perfectly for validating a users input option against allowed options..
example:
validateInput "1" "1 3 4 5" would return 0 (success)
function validateInput {
input=$1
allowedInput=$2

I'm obviously very new to this. I'm trying to write a simple for loop that will read the directory names in /Users and then copy a file into the same subdir in each user directory.
I have this, and it works but it isn't great.

HOMEDIRS=/Users/*
for dirs in $HOMEDIRS; do

Thank you for taking the time to look at this and provide input.
To start, I am not a linux/unix expert but I muddle through the best I can.
I am also in no way shape or form a programmer. Please keep that in mind as you read this script.
This script is designed to find all files in a given... (8 Replies)

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.
