Thanks for checking in.

Do you know how too let this script ask me which program i want to check.

eg
$ "command"
$ echo "Monitor processes for which program"
$ output....

#Checking processes
ps -ef |grep fglgo > f1
cat f1 |cut -c 1-8 > a.1
cat f1 |cut -c10-14 > b.1
paste a.1 b.1 > B
cat f1 |cut -c49-72 > c.1
paste B c.1 > final
echo "STARTING TO CHECK"
echo "3"
sleep 1
echo "2"
sleep 1
echo "1"
cat final |more
rm f1
rm a.1
rm b.1
rm c.1
rm B
rm final

maybe substituation right in the begining will help.

2nd Script

PN=`basename "$0"`                      # Program name
VER=`echo '$Revision: 1.2 $' | cut -d' ' -f2`

# Determine mail spool directory (BSD/SYSV)
for MailDir in /tmpx
do
    [ -d "$MailDir" -a -r "$MailDir" ] && break
done

Usage () {
    echo >&2 "$PN - show top 10 directory users, $VER (hs '94)
usage: $PN [directory ...]

If no directory is specified, $MailDir is the default."
    exit 1
}

[ $# -gt 0 -a "$1" = "-h" ] && Usage

# set the default directory
[ $# -lt 1 ] && set $MailDir

echo "NAME                     BYTES    FILES   PERCENT"
ls -lL "$@" |
    awk '
        (NF == 8 || NF == 9 ) {                 # BSD or SYSV
            # example of a line:
            # -rw-------  1 andrea     286282 Oct 21 11:24 andrea
            #           or
            # -rw-------  1 andrea entw  286282 Oct 21 11:24 andrea
            Usage [$3] += $(NF-4)       # used bytes, username is index
            Count [$3]++
            TotalBytes += $(NF-4)
        }
        END {
            for ( user in Usage )
                printf "%-15s %12d      %d      %2d\n", \
                    user, Usage [user], Count [user], \
                    Usage [user] * 100 / TotalBytes
        }
    ' | sort -nr +1 | head
exit 0

same with this one how do i let this script ask me which dirrectory i would like to take a look at.

At the momment it only checks /tmpx

Thanks in advance

Well, to ask a questions, and record the answer in memory, use the "read" builtin command. Here's an example (I wrote it in sh instead of ksh, since I don't know which you're using, if either- this should be portable between the two, with the exception of the echo statement):

#!/bin/sh
# Simple example to read in a line, then echo it out

# If you're using Linux, you'll need to use "echo -e"
# instead of "echo".

echo "Enter a string: \c"

# The \c tells echo not to add a new line

read input

# That's where it takes your input and stores it into the 
# variable "input" - you can name this whatever you want

echo "\nThe \$input variable was: $input"

# The "\n" forces echo to insert a new line at that spot

Of course this script isn't of much use to anyone, but it gives an example of using read.
Hope that helps.

Thanks allot this realy helped, you have no idea.

FINAL SCRIPT if you are interested

#!/bin/sh
# Simple example to read in a line, then echo it out
# If you're using Linux, you'll need to use "echo -e"
# instead of "echo"--> UNIX.

echo "Please Enter The Program Name: \c"

# The \c tells echo not to add a new line

read PROG

# That's where it takes your input and stores it into the
# variable "PROG" - you can name this whatever you want

echo "\nThe \$PROG variable was: $PROG"

# The "\n" forces echo to insert a new line at that spot
#Checking processes
ps -ef |grep "$PROG" > f1
cat f1 |cut -c 1-8 > a.1
cat f1 |cut -c10-14 > b.1
paste a.1 b.1 > B
cat f1 |cut -c49-72 > c.1
paste B c.1 > final
echo "STARTING TO CHECK"
echo "3"
sleep 1
echo "2"
sleep 1
echo "1"
cat final |more
rm f1
rm a.1
rm b.1
rm c.1
rm B
rm final

Thanks.
