Bash alias: command not found

问题

I'm trying to setup a simple alias to move me into my Developer folder on my machine. However, after setting it up, I get a weird error:

-bash: dv: command not found

I setup my alias in .bashrc like so:

alias dv='cd Developer/'

I use it by just typing dv, and then get that error. Does anyone see any syntax errors or something I'm missing here for aliases?

回答1:

Run bash and then try the command.

Alternatively, put it in ~/.bash_profile which should be loaded automatically.

回答2:

.bashrc is only read on startup. If you just modified your .bashrc then you need to get a new shell or get your current shell to see the changes applied:

• source ~/.bashrc in your current shell (although this may cause some startup items to run twice, which could cause other issues)
• exec bash to get a new shell
• just open a new Terminal window

回答3:

Make sure the following line is present inside .bash_profile

test -f ~/.bashrc && . ~/.bashrc

If not then add it to the beginning. This code is used by .bash_profile to load up .bashrc. If this line is not present inside .bash_profile then anything you type inside .bashrc will not be loaded.

Error:

-bash: alias: cd /opt/logs: not found alias log= "cd /opt/logs"

Solution :

Ensure there is no space after the = symbol

log="cd**  /opt/logs"

回答5:

Another solution is to call your command with bash using -i -c option:

bash -i -c my_alias

I had the same issue but the weirdest solution. I was copying it from Windows machine to OS X and for some reason, the spaces used were different and when I replaced them with normal spaces, it worked. It was not tabs, I have no idea what it was.
