Why does this simple bash code give a syntax error?
- by Tim
I have the following bash code, which is copied and pasted from "bash cookbook" (1st edition):
#!/bin/bash
VERBOSE=0;
if [[ $1 =-v ]]
then
VERBOSE=1;
shift;
fi
When I run this (bash 4.0.33), I get the following syntax error:
./test.sh: line 4: conditional binary operator expected
./test.sh: line 4: syntax error near `=-v'
./test.sh: line 4: `if [[ $1 =-v ]]'
Is this as simple as a misprint in the bash cookbook, or is there a version incompatibility or something else here? What would the most obvious fix be? I've tried various combinations of changing the operator, but I'm not really familiar with bash scripting.
