scripting - Terminate shell code while it is running -

-

for clearing screen in shell code if write ctrl + l 

printf "\033c"

then shall done ctrl + c ?

just exit not working in code because handling errors , in case of bad inputs have run code again , when unseting variables unset working fine later again code shows output no input variables.

if understand correctly want do, should use trap command. trap prevent shell default handling , allows interrupt, quit, hangup etc. doing.

the syntax following

trap <command execute> <signal intercept>

so like

trap break int

to have equivalent of ctrl-c.
