Now before you flag this as a duplicate please understand i did search for this problem and i already tried all of the solutions to no effect.

My script:

#!/bin/bash

echo "Enter the number 3"
read t1
if [$t1 -eq 3]; then
    echo "it is 3"
elif [$t1 > 3]; then
    echo "it is greater than 3"
fi

exit 0

The error i get is:

./g.sh: line 5: [3: command not found
./g.sh: line 7: [3: command not found

Fivesheep

spaces needed if [ $t1 -eq 3 ]

linux - Bash & 'su' script giving an error "standard in must be a tty"

linux bash shell shell-script

Folks, I'm having an issue with a bash script which runs a particular command as a different user.

The background: Running on a Linux box (CentOS), the script is quite simple, it's starting the hudson-ci application.

declare -r HOME=/home/hudson
declare -r RUNAS=hudson
declare -r HOME=/home/hudson
declare -r LOG=hudson.log
declare -r PID=hudson.pid
declare -r BINARY=hudson.war

su - ${RUNAS} -c "nohup java -jar ${HOME}/${BINARY} >> ${HOME}/${LOG} 2>&1; echo $! > ${HOME}/${PID}" &

This is the abridged version of the script, when run, the script exits with "standard in must be a tty". Any ideas on what I could be doing wrong? I've tried Dr Google and all the advice hasn't helped thus far.
