better, simpler searching and scripting with bash globstar \u00ab ShellRunner<\/a><\/p>\n
Globstar is a feature not typically enabled, but present in bash 4+, and it allows you to do more easily select files in bash, using a double star **.<\/p>\n
For example, if you want to every .text file, in all subdirectories, you no longer even need to use the find command.<\/p>\n
ls **\/*.text<\/pre>\nThe ** here will traverse any number of directories, not just the current directory. Here\u2019s another very useful, easy to remember example. Ever want to find a line of text somewhere in a huge pile of files, but you know some part of the file name? You can do a recursive grep to easily find it, without some abstruse find command.<\/p>\n
grep -r needle **\/*haystack*<\/pre>\nTo begin using globstar, you need to enable it. It should be the default, if you ask me, but enabling is simple. From the terminal, type:<\/p>\n
shopt -s globstar<\/pre>\nYou\u2019ll probably want to add that line to your ~\/.bashrc file, too, so it\u2019s enabled every time you open a terminal or login.<\/p>\n
