Hi I'm new to bash scripting. Just wrote this simple program but it is throwing error.
#!/bin/bash os=`uname -o` echo $os if ["$os"=="GNU/Linux"] ; then echo "Linux" else echo "Windows" fi Using == or -eq for both cases I'm getting the following error and it is printing the else condn.
./ostype.sh: line 3: [GNU/Linux==GNU/Linux]: No such file or directory
Windows
Bash version : GNU bash, version 3.2.48(1)-release (x86_64-suse-linux-gnu)

try
if [ "$os" = "GNU/Linux" ] note the spaces, and the single =.
[ is actually a program, and the rest are arguments!
Use = for string comparison. See:
Also, there should be a space around the square brackets and the comparison operator, i.e.
if [ "$os" = "GNU/Linux" ]; then ^ ^ ^ ^ ^ | | | | | \-\-----\-\-----------\-- (need spaces here)
