Hi, I'm providing you with a script I wrote, that can ease installing the ports packages:
The script is written in bash, and I would love to have some input feedbacks... so you can freely test it and let me know if you like it or not.

Code:
#!/bin/bash
# This bash script is used to search for packages on a freebsd system
# - output: directories that match the input (if only one, automatically cd into it)
# - input: <package_name> [arguments]
# - input args:
# -l: insert left '*' to match package name
# -r: insert right '*' to match package name
# -b: insert left and right '*' to match package name
# Prerequisite commands: bash, find, cd, echo, wc
#
# Global variables
