List installed packages

[marinecomm]

I came across this code to make a list of all installed packages and the write it to a text file if you want it to. The problem is that sometimes the code works and sometimes it doesn't. I can't figure out why it doesn't work sometimes. The code is:

./user_installed_packages

When it doesn't work I get the following error message: bash: ./user_installed_packages: No such file or directory

Any thoughts or ideas as to what could be causing it? I'm running Xubuntu 12.04 64-bit.

If you follow the link in my signature there's a description.

The command ./user_installed_packages says "run the program (or script) called user_installed_packages that's in the current directory" - so if the file is not in the current directory, you'll get that error. You can see what the current directory is by typing

pwd

and you can list the contents (to check the user_installed_packages file is there) using

ls

If you want to be able to run the program/script regardless of what directory you're in, you should put it in a directory that's on your executable path e.g. /home/username/bin (for personal programs) or /usr/local/bin (for everyone). You can check the current executable search path using

echo $PATH
