Linux please. bash shell.

$1.$Your script will then solve each of these Command Substitution exercises. You need to use the variable in all paths.

a$.$Use grep to search the contents of all files in your ~$/$Documents$/$cis$190$ directory for the string $$bash$$ make sure that the grep output is only the filename and not the line that was matched. Use command substitution to use this output as a list of files for $$ls $-$lh$$ giving you a way to get the long listing human readable results for a list of files that was generated by grep and substituted in here! This is a cool use of command substitution :)

b$.$Create a variable called cs$1$ and store the results from running exercise $2$a above.

c$.$Echo the contents of the cs$1$ variable.

d$.$Create a variable called cs$2$ and store in it the contents of the $PATH variable use command substitution to accomplish this.

e$.$Echo the contents of the cs$2$ variable.

f$.$Use the cs$2$ variable and add the contents of the dirname variable to the beginning of the cs$2$ variable and separate it from the other contents with a : but don$$t lose the current contents. This is not as hard as you are probably thinking!

g$.$Echo the contents of the cs$2$ variable.
