A Linux administrator recently changed the IP addresses of all the web servers from 10.10.50.x to 10.10.100.x. The administrator needs to update the serverlist.txt file to reflect the change. The…

This command would print the modified content to standard output but would not save the changes back to the `serverlist.txt` file because it lacks the `-i` option for in-place editing.

The `sed` command does not have a `-g` option for global replacement; instead, the `g` flag is placed at the end of the substitution command (e.g., `s/old/new/g`), and the `a` flag is not a standard substitution flag.

The `sed` command with the `-i` option modifies the file in place, and the substitution command `s/.50/.100/` finds the first instance of ".50" on each line and replaces it with ".100", correctly updating the IP addresses for the web servers.

While `sed -i 's|.50|.100|g'` would also accomplish the task, the `g` flag (global replacement) is redundant in this specific case because the target pattern ".50" appears only once per relevant line for the IP address.
