Hi,
When I execute my shell scrip below I get the following:
+ cc_started=false
+ CC_PATH=/home/eraonel/pub/cruisecontrol-bin-2.5
+ '[' -ne 0 ']'
./checkLocalCC.sh: line 8: [: -ne: unary operator expected
+ echo 'local installtion of cc is up and running [ ]'
local installtion of cc is up and running [ ]
What am I doing wrong here?
by the way line 8 is:
if [ $cc_exists -ne 0 ]; then
Tell me, what would the if statement expand to if the variable
$cc_exists is not set or is set to spaces or an empty value?
cheers,========

======
#!/bin/sh

CC_PATH=$HOME/pub/cruisecontrol-bin-2.5

Hmmm^2
