using find command in linux
#!/usr/bin/env bash
# different ways to use the linux find command preferred choice typically.
find . -exec grep chrome {} +
#find will execute grep and will substitute {} with the filename(s) found. The difference between ; and + #is that with ; a single grep command for each file is executed whereas with + as many files as possible #are given as parameters to grep at once.
#If you use the \; ending construct grep is passed one file at a time, so it doesn't display the file name by default, only the matched lines. To get a file list instead add use grep -ls inside of the find construct.
