linux - How to concatenate two strings to build a complete path
I am trying to write a bash script. In this script I want user to enter a path of a directory. Then I want to append some strings at the end of this string and build a path to some subdirectories.
For example assume user enters an string like this:

The POSIX standard mandates that multiple / are treated as a single / in a file name. Thus
//dir///subdir////file is the same as /dir/subdir/file.
As such concatenating a two strings to build a complete path is a simple as:
full_path="$part1/$part2"
