bash symlink files matching glob

ByAnurag batra July 21, 2022October 23, 2022

# Basic syntax:
ln -s /source/files/*.bar /destination/directory/
# Where:
#	- -s makes symbolic links instead of hard links
#	- symbolic links to the files ending in .bar in the /source/files/ directory
#		are made in the /destination/directory/

Here is what the above code is Doing:
1. The ln command is used to create links between files.
2. The -s option tells ln to create a symbolic link instead of a hard link.
3. The first path is the source file, and the second path is the destination.
4. The * wildcard is used to match all files ending in .bar in the /source/files/ directory.
5. The symbolic links are created in the /destination/directory/ directory.
