When given one ormore filenames on the command line, this program uses the strings program (which isincluded in the GNU binutils package) to generate a list of readable text “words” in eachfile. The for loop processes each word in turn and determines if the current word is thelongest ...
Hopefully, these examples have demonstrated the power of aforloop at the Bash command line. You really can save a lot of time and perform tasks in a less error-prone way with loops. Just be careful. Your loops will do what you ask them to, even if you ask them to do something destr...
