awk command return not found on Ubuntu desktop but work well on Centos

I create test.sh to read a file with content

item1:return1
item2:return2
...
item10:return10

test.sh content

VAR1=$1
VAR2= `grep "^${VAR1}:" /home/path/file | awk '{print $2;}'`

echo "${VAR2}";

run test

sh test.sh item1

return

: not found test.sh: 
: not found test.sh: 

When I run the same on Centos. return

return1

What's wrong with awk command ?

Nothing is wrong with awk command. Your issue is test.sh cannot be found as message shows. CentOS probably sets your path to PATH variable.

Run it as sh ./test.sh item1 (I assume test.sh is in your current directory)

Edit: I should have paid better attention to the script, : in grep is the issue This works

VAR1=$1
VAR2=`grep "${VAR1}\:" file | awk '{print $2}'`
echo "${VAR2}";

However, awk by default does not recognize : as a separator, I had to use

item1: return1
item2: return2

I have no idea how it could work on server or centos without this change
