This next example is similar, but here I use the -i argument to the grep command, telling it to ignore the case of the characters string, so it will find files that contain string, String, STRING, etc.:
find . -type f -name “*.java” -exec grep -il string {} \;
This command searches through the /usr/local directory for files that end with the extension .html. When these files are found, their permission is changed to mode 644 (rw-r–r–).
find /usr/local -name “*.html” -type f -exec chmod 644 {} \;
This command searches through the htdocs and cgi-bin directories for files that end with the extension .cgi. When these files are found, their permission is changed to mode 755 (rwxr-xr-x). This example shows that the find command can easily search through multiple sub-directories (htdocs, cgi-bin) at one time.
find htdocs cgi-bin -name “*.cgi” -type f -exec chmod 755 {} \;
From time to time I run the find command with the ls command so I can get detailed information about files the find command locates. To get started, this find command will find all the “*.pl” files (Perl files) beneath the current directory:
find . -name “*.pl”
In my current directory, the output of this command looks like this:
./news/newsbot/old/3filter.pl
./news/newsbot/tokenParser.pl
./news/robonews/makeListOfNewsURLs.pl
That’s nice, but what if I want to see the last modification time of these files, or their filesize? No problem, I just add the “ls -ld” command to my find command, like this:
find . -name “*.pl” -exec ls -ld {} \;

To perform a case-insensitive search with the Unix/Linux find command, use the -iname option instead of -name. So, to search for all files and directories named foo, FOO, or any other combination of uppercase and lowercase characters beneath the current directory, use this command:
find . -iname foo
If you’re just interested in directories, search like this:
find . -iname foo -type d
And if you’re just looking for files, search like this:
find . -iname foo -type f

To find all files modified on a certain date, for example, ‘2007-06-07’ the final input is:
find . -type f -newermt 2011-04-20 ! -newermt 2011-04-21
Search for files in your home directory which have been modified in the last twenty-four hours. This command works this way because the time since each file was last modified is divided by 24 hours and any remainder is discarded. That means that to match -mtime
0, a file will have to have a modification in the past which is less than 24 hours ago.
find . -mtime 0
