Similarly, use the —B flag to print the line before a matching pattern. In this example, we are using the grep —B1 with pattern 4 grep —B1 4 filename. See the command below:. Note that, instead of A1 or B1 you can use any positive integer number with the dash —A or—B flag. It will print that number of lines after and before the matching pattern.

Lastly, the —A and —B i. Skip to content Search for: Search Close. Close Menu. Thank you for reading this post. Kindly share it with others. Connect with D. I allow to create an account.

The find command will begin looking in the starting directory you specify and proceed to search through all accessible subdirectories. You may specify more than one starting directory for searching. By default, multiple options are joined by "and". You may specify "or" with the -o flag and the use of grouped parentheses.

To match all files modified more than 7 days ago and accessed more than 30 days ago, use:. You may specify "not" with an exclamation point. 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.

When these files are found, their permission is changed to mode rwxr-xr-x. This example shows that the find command can easily search through multiple sub-directories htdocs , cgi-bin at one time:.

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. 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:. The "-l" flag of the ls command tells ls to give me a "long listing" of each file, while the -d flag is extremely useful in this case; it tells ls to give me the same output for a directory.

Normally if you use the ls command on a directory, ls will list the contents of the directory, but if you use the -d option, you'll get one line of information, as shown above. Be very careful with these next two commands. If you type them in wrong, or make the wrong assumptions about what you're searching for, you can delete a lot of files very fast. Make sure you have backups and all that, you have been warned.
