How Find Only Executable Files Using 'locate'?
Introduction
The locate
command is a powerful tool used to search for files on a Linux system. It's often used in conjunction with the updatedb
command to create a database of files on the system. However, by default, the locate
command searches for all types of files, including executables, non-executable files, and even directories. In this article, we'll explore how to use the locate
command to find only executable files.
Understanding the Problem
When you run the command locate gtags
, it will find all the files named gtags
, regardless of their type. This can be a problem if you're only interested in finding executable files. For example, if you have a file named gtags
that's a script, but not an executable, you might not want to include it in your search results.
Using the -e
Option
To find only executable files using the locate
command, you can use the -e
option. This option tells locate
to search only for executable files. Here's an example:
locate -e gtags
This command will find all the executable files named gtags
on your system.
Using the --regex
Option
If you want to search for files that match a specific pattern, you can use the --regex
option. This option allows you to use regular expressions to search for files. Here's an example:
locate --regex 'gtags{{content}}#39;
This command will find all the files that end with the string gtags
.
Using the --ignore
Option
If you want to exclude certain files from your search results, you can use the --ignore
option. This option allows you to specify a pattern to ignore. Here's an example:
locate --ignore 'gtags\.sh{{content}}#39; gtags
This command will find all the files named gtags
, but will exclude any files that end with the string gtags.sh
.
Using the --not
Option
If you want to find files that do not match a certain pattern, you can use the --not
option. This option allows you to specify a pattern to exclude. Here's an example:
locate --not 'gtags\.sh{{content}}#39; gtags
This command will find all the files named gtags
, but will exclude any files that end with the string gtags.sh
.
Conclusion
In this article, we've explored how to use the locate
command to find only executable files. We've covered the -e
