I am providing a shell script file find$\_$a$\_$out. sh that repeatedly searches for files named a$.$ out under the current folder and sends the results to files$\_$to$\_$remove.txt$.$

Note: You don't need to fully understand this script for now because we will have extensive discussion of shell scripting later.

$4\mathrm{.}1.$ Locate that script in a gist of mine.

$4\mathrm{.}2.$ On Google Cloud, click the "Open Editor" graphic. Create a new file find$\_$a$\_$out.sh and copy the code from my gist, save the file.

$4\mathrm{.}3.$ Make the file executable, and test it out.

$>$ chmod $+xfin{d}_a{?}_{o}ut.sh$

$>\frac{.}{f}in{d}_a{?}_{o}ut.sh\frac{?}{?}$# press $ctrl+cto$ terminate a running script

$>$ cat $file{s}_t{o}_r$emove.$txt$
