描述

It looks like fuck doesn't handle pipes well. If I try to do this in Bash:

$ pss -ef | grep foo
-bash: pss: command not found
$ fuck
ps -ef | grep foo
ps: illegal argument: |
usage: ps [-AaCcEefhjlMmrSTvwXx] [-O fmt | -o fmt] [-G gid[,gid...]]
          [-g grp[,grp...]] [-u [uid,uid...]]
          [-p pid[,pid...]] [-t tty[,tty...]] [-U user[,user...]]
       ps [-L]

It looks like the command is executed in the wrong way, it seems like it's trying to execute it as a single command, instead of treating it as a line of input with potentially multiple commands.

研究方向
Investigate how thefuck parses and executes corrected commands. The issue suggests that commands with pipes are not handled correctly. Look at the command splitting logic in the shell modules (e.g., thefuck/shells/bash.py). Reproduce the bug using the provided example: 'pss ef | grep foo'. Check if the pipe argument is being passed as part of the command to ps. Consider adding handling to split on '|' and execute as a pipeline. Reference comments in the issue for additional context.
