“There are several commands available on the command
line to locate files and folders on the file system. This article
reviews three of them, viz whereis ,locate. find.“1) whereis
This command can search for the binary, source, and manual page
files for a comand$ whereis whereis
whereis: /usr/bin/whereis /usr/share/man/man1/whereis.1.gz“2) locate: locate uses a database created by an updatedb to
efficiently locate files. Works great, assuming your database is
updated often enough to be reasonable upto date. Most boxes using
locate have the updatedb occuring in cron. On my ubuntu box, I got
a long list of files when I tried to locate command.”
