Is there a TRY CATCH command in Bash?
No.
Bash doesn't have as many luxuries as one can find in many programming languages.
There is no try/catch
in bash; however, one can achieve similar behavior using &&
or ||
.
Using ||
:
if command1
fails then command2
runs as follows
command1 || command2
Similarly, using &&
, command2
will run if command1
is successful
The closest approximation of try/catch
is as follows
{ # try
command1 && #save your output } || { # catch # save log for exception }
