Bash script with regex not behaving on Ubuntu
- by user265330
I have a Bash script that is working on my OpenSuSE box, but when copied across to my Ubuntu box, is not working. The script reads in from a file. The file has fields separated by white space (tabs and spaces).
#!/bin/bash
function test1()
{
while read LINE
do
if [[ $LINE =~ "^$" || $LINE =~ "^#.*" ]] ; then
continue;
fi
set -- $LINE
local field1=$1
local field2=$2
done < test.file
}
test1
with test.file containing:
# Field1Header Field2Header
abcdef A-2
ghijkl B-3
There seem to be two problems:
(1) $field2, the one with the hyphen, is blank
(2) The regex to strip out the blank lines and lines that start with # is not working
Anyone know what's wrong? As I said, it works fine on OpenSuSE.
Thanks,
Paul
