Supposing someone invokes a non-existent command, the only way I know to retrieve its error status from a script I execute right after is by using
I.e., let's say this script's name is
dummy where its contents are simply
#!/bin/bash echo $?
I know I will only get the exit status I'm looking for (127) if I invoke
source dummy, but is there another way to facilitate getting the exit status (preferably without using
alias) from the last command from within the script, without using
source so I could simply call
dummy to get my desired behaviour?
I am simply trying to make a script to check for a typo in the previous command. This requires detecting the previous exit status to make sure there was a potential typo in the first place, so I need to be able to get the exit status of the last command from within the script. I am also hoping to minimize the amount of setup a user would have to do, so that a user could simple invoke
dummy, for example, and the rest would be taken care of. This is my reason for trying to avoid
My initial test for exit status of the last command was to use
#!/bin/bash ESTATUS=$? # Saved exit status for later echo $ESTATUS
but this required having to run that script with
source. Is there a good way to replicate this without having to use
