When I was new to shell scripting, I used a lot of short tests instead of if statements, like false && true.
Then later I learned using set -e, and found my scripts were dying for some reason, and they would work if I replaced the short tests with full if statements. Now, the time has gone, and I still use full if statements only.
The most interesting is that if I open an interactive shell and do the following:
set -e
false && true
echo $?
it returns 1 but the shell doesn't die!
I see that I have been wasting too many lines of code. Anyone could explain to me how can I use set -e with short tests safely, eg. without the script dying?
