ipython shell awk : Escaping "$" sign

2018-06-16 19:43:41

I am figuring out the Ipython shell support. Its seems awk doesn't work ie following command

!ls -l | awk '{print $1}'

just prints "1".

How do I pass the "$" sign correctly to shell. I am using zsh.

两个美元符号给你一个字面的美元符号，所以试试：

!ls -l | awk '{print $$1}'

尝试将$转义为$

!ls -l | awk '{print $1}'
