How to compare a string value in an IF else condition using shell script

Question

#!/bin/sh

if [ $# -lt 2 ] then echo "Usage $0 servername envtype" exit 1 fi

servername=$1 envtype=$2 srv=echo $servername | tr "a-z" "A-Z" srvtype=echo $envtype | tr "a-z" "A-Z" echo $srv echo $srvtype

if [ "${srv}" <> "SCP" ]; then if [" ${srv}" <> "RENTD" ]; then echo "Invalid servername" exit 1; fi fi

I am getting this error when running the shell script

[ 2 -lt 2 ]
servername=scp
envtype=prd
echo scp
tr a-z A-Z
srv=SCP
echo prd
tr a-z A-Z
srvtype=PRD
echo SCP SCP
echo PRD PRD
[ SCP ]
[ SCP ] /tmp/testupper.sh: 19: [ SCP: not found

Glad you found your issue. Your question formatting doesn't reflect what is code as opposed to text (eg, your actual "I am getting this error..." Could you Edit your question (from the Share Edit Follow Flag set of links? In edit mode, highlight the code and click the { } button to format it. (Really, all that does is put 4 spaces in front of each line of code, but that's all markdown needs.) See also stackoverflow.com/editing-help for other available formatting in questions and answers. And, even though you found your answer, it's still worth editing for posterity — Randall

Found my issue.

[" ${srv}" <> "RENTD" ]

there is a space being prefixed to the srv variable, between the " and the $: " ${srv}"

Right - spaces are usually not syntactical in sh (ie, POSIX family) shells, but inside quoted strings they are always literal characters.

Also - make sure you know what sh-shell you are really using. One way is with this oneliner: which sh | xargs ls -la . That should show you where the symlink sh is really pointing.
