Hi I have about a 100 files in a folder and I want to change the file permissions to read write and execute for each file in this folder.
I know how to change the file permissions for a single file i.e. chmod a+rwx foo.txt but not for a group of files. Please help me out
Thank you!

To modify the permission flags on existing files and directories, use the chmod command ("change mode"). It can be used for individual files or it can be run recursively with the -R option to change permissions for all of the subdirectories and files within a directory.
Chmod allows you to change the permission of multiple files and subdirectories within a directory using the –R option as follows: $ chmod –R [reference][operator][mode] file... Let's say the subdirectories under the downloads directory have the following permissions as shown in the following screenshot.
To change file and directory permissions, use the command chmod (change mode). The owner of a file can change the permissions for user ( u ), group ( g ), or others ( o ) by adding ( + ) or subtracting ( - ) the read, write, and execute permissions.
If you need to change a file permission, use the chmod command. It also allows to change the file permission recursively to configure multiple files and sub-directories using a single command.
you can use wildcards, like
chmod a+rwx *.txt
or
find <directory> -type f -exec chmod a+rwx {} \;
the last command will find all files and exec the chmod per each file.
however, having a+rwx is not recommended at all
