I came up with this solution to check if variable $line starts with a
hash. Basically I am checking if line is a comment in the configuration
file.
#!/bin/sh
if expr "${line}" : '#.*' > /dev/null; then
echo Ignoring comment line
fi
I had to redirect to /dev/null, because expr prints a number to STDOUT.
Is there a better way to do this kind of string matching check in
/bin/sh (not bash)?
Thanks
