Failed to successfully execute some commands in Cygwin

Question

I installed Cygwin64 on my 64-bit Windows 7 machine. However, the following commands did not execute, displaying the error messages below. Could you help in granting permission?

$ ll
-bash: ll: command not found

$ clear
-bash: clear: command not found

However, the ls -l command worked ...

$ ls -l
total 0

I also tried without commenting on the next line in the .bashrc file in my home directory -

# alias ll='ls -l'

But that didn't help either!

Answer 1

After you uncomment the alias, you must run the new Cygwin shell for it to take effect. The file .bashrcis actually a script that is created when bash starts.

clear Cygwin (Unix). Ctrl-L.
