Shell script to run x times
Hi,

First i need to cd to this directory $SWDIR/util
Second i need to run the following either 4 times or 20 times

./swadm add_process 1 BG Y

how can i put this in a script which should ask for user input on how many times you want to run this

Thanks,

Code:
cd $SWDIR/util
cntr=1
while [ $cntr -lt 21 ]; do
./swadm add_process 1 BG Y
cntr=$(( cntr + 1 ))
done

Script to run it N times. You get the idea for the 4/20 times scenario.

Code:
#!/bin/bash
TIMES=$1
cd "$SWDIR/util"
for((i=0; i < TIMES; i++)); do
  ./swadm add_process 1 BG Y
done

$ thescript.sh 20

With user input:
Code:
#!/bin/bash
read -p "How many times ? " N
cd "$SWDIR/util"
for((i=0; i<N; i++)); do
  ./swadm add_process 1 BG Y
done

Code:
cd "$SWDIR/util" || exit 1  ## exit if cd fails
printf '%s ' "Number of times to run?"
read num
n=0
while [ $n -lt $num ]
do
  ./swadm add_process 1 BG Y
  n=$(( $n + 1 ))
done
