To display the contents of a text file in a shell script, you can use the cat command. cat is a utility that displays the contents of one or more text files to the standard output (usually the terminal).
To display the contents of a text file with cat, simply specify the file name as an argument to the cat command:
cat /path/to/file
This will display the contents of the /path/to/file file to the terminal.
If you want to display the contents of multiple files, you can specify the file names as additional arguments:
cat /path/to/file1 /path/to/file2
This will display the contents of both /path/to/file1 and /path/to/file2 to the terminal.
You can also use the cat command to concatenate the contents of multiple files and output the result to a new file:
cat /path/to/file1 /path/to/file2 > /path/to/output/file
This will concatenate the contents of /path/to/file1 and /path/to/file2, and write the result to /path/to/output/file.
For more information about using the cat command to view and manipulate text files on a Linux or Unix system, you can consult the cat documentation or seek assistance from a qualified Linux or Unix administrator.
