Debugging bash scripts is pretty straightforward, throwing around a couple echo and set -x quickly gives you what you need. But what if you want to add a nice breakpoint, debugging to lots of paces in the code or turn all debugging on or off at once? Then this little script I wrote is the right thing for you: debug.sh just download it to the same directory as your script and include it with the following line:
It contains 4 simple functions that will make your bash coding easier.
debug and breakpoint both print the argument with a timestamp to STDERR
You can turn off all the functions by adding a DEBUG=false into your code
Example:
Select All Code:
#!/bin/bash . debug.sh debug_on echo foo debug_off debug "I am a test" breakpoint "wait for a bit" echo done
Output:
Select All Code:
+ echo foo foo + debug_off + true + set +x [16:37:47] I am a test [16:37:47] -breakpoint- wait for a bit press any key to continue done
