Indeed, the bash linux terminal is very closely related to the bash script language. The grep command needs to be modified accordingly, putting the other character used as a separator in place of “:”. In the rare case in which some of the files contain the character “:” as part of their name, we can use the -F argument of the file command to use some character other than the “:” character as the separator.

In other words, the expression means “search for a : in the file command output followed by any number of characters “.*” and then the sub-string ” text”.

The expression “.*” ensures that the sub-string ” text” is only searched in the file type description, not in the filename. Luckily for you, there are multiple ways of finding text into files on Linux but the most popular command is the grep command. What I want to do is search that part in the file. The subsequent grep command filters all files with “ASCII text” or “UTF-8 Unicode text” as part of the file type description. The file * command prints a list of filenames followed by the file type description of all files in the current directory. We can quickly list all text files in the current directory using a simple command: file * | grep ".* text"
