I am using Ubuntu on VMWare but I cannot connect to internet because of security restrictions.
I was wondering if there was a way to search for strings through the terminal and find which line the string is located on within the file.

The best I use is grep command with options -ri (Recursive and case insensitive search):
$ grep -r <text_pattern_to_search> directory_or_path_to_search
options that might be useful to you:
-i - case insensitive -r, --recursive like --directories=recurse -R, --dereference-recursive likewise, but follow all symlinks --include=FILE_PATTERN search only files that match FILE_PATTERN --exclude=FILE_PATTERN skip files and directories matching FILE_PATTERN --exclude-from=FILE skip files matching any file pattern from FILE --exclude-dir=PATTERN directories that match PATTERN will be skipped.
for deep info you can do
man grepin linux terminal.
If you want to find only line number where the sting is located within the file use this:
grep -n '/string_To_Find/=' directory/file_Name
If you want to find line number and also output the full line name where the string is located in the line use this:
grep -n 'string_To_Find' directory/file_Name
And if you only want to find full line name where the string is, use this:
grep -r 'string_To_Find' directory/file_Name
