在bash.bashrc中设置别名

Question

When I try to set aliases, I get two different results using two different methods. I'm using cygwin.

METHOD 1:

In cygwin I execute the following:

alias python='/cygdrive/c/python27/python.exe'

python <name of python file>

...and it runs just fine, as expected

METHOD 2:

In my bash.bashrc file I add the following line:

alias python='/cygdrive/c/python27/python.exe'

python <name of python file>

...and I get the following error:

:no such file or directoryython.exe

Just two questions: What is the difference between these two methods? Why is one causing and error and one is not? Thanks <3

Answer 1

The error indicate that the bash.bashrc file was not loaded.

Check these:

1. The bashrc filename is usually .bashrc / .bash_profile and it's in the user's home directory. Or it should exists as /etc/bash.bashrc .
2. The file is not loaded automatically, restart the shell to load it.

Answer 2

See how this error is all confused looking?

:no such file or directoryython.exe

Your bash.bashrc file has DOS line endings. Go fix that.
