[Nagiosplug-help] Strange problem with Bash, AWK and check_http

[Edward Blum]

FIXED!

With a little research and when running check_http with -v I see the line

 is 135 charactersktrace.co.uk:80/SetupHHRImporter1020.exe

For some reason the variable had a funny hidden character of some sort in
which check_http doesn't like.

I cleansed the variable with:


fileName=$(echo $fileName | egrep "[a-z,A-Z,.,0-9]{1,}" -o)
