shell - Prevent a command in a shellscript from being executed inside another shellscript -

-

i invoking shellscript inside shellscript, , invoked 1 has command delete folder, don't want executed, this

$ rm ../temp -rf

is there way prevent command being executed without changing invoked script contents?

you can define alias in script:

alias rm='echo safe'

by default aliases work in interactive shells, must change behaviour with:

shopt -s expand_aliases

in script , source other script (the 1 cannot change):

source the_other_script.sh

or

. the_other_script.sh

this work unless other script runs rm in sub-shell.

another, safer method create own rm command nothing (or prints out argument know what's going on), put directory , put directory first 1 in path environment variable (korn shell syntax):

$ export path=/path/to/your/dummy/rm/replacement:$path
