set temp = "sunny45"
if [ - z $temp ]; then echo "empty" ; else echo "not empty" ; fi
The above code is giving below error when i tried this code on unix terminal
if: Expression syntax.
Please suggest should i source any thing in file and what should ne the file name of this code present.
Wipe spaces around equal sign and between - and z, then enclose variable in double-quotes:
temp="sunny45"
if [ -z "$temp" ]; then echo "empty" ; else echo "not empty" ; fi
You have multiple syntax errors. Probably try with http://shellcheck.net/ before asking for human help.
set will not set a regular variable. I'm guessing you want
temp="sunny45"
where you need to make sure there is no whitespace on either side of the equals sign.
The -z in the test similarly needs to be a single token, with no internal whitespace. You also need to quote the variable.
if [ -z "$temp" ]; then
