一句话：
像python那样，在''里面使用'\'abc\''，在bash中不行
需要把
\'
换成
'\''
这样问题解决
You can make that command into a Bash alias by editing your shell configuration file (typically ~/.bashrc or ~/.bash_aliases).
Here’s the step-by-step procedure:
1. Open your .bashrc (or .bash_aliases) file
nano ~/.bashrc
2. Add the alias definition
At the end of the file, add a line like this:
alias qbstat='ps aux | grep qbittorrent | awk '\''{printf "%-7s %-7s %-20s\n", $1, $2, $12}'\'''
Explanation:
-
You need to escape single quotes properly because of the nested quoting.
-
The
'\''sequence is how you embed a literal'inside a single-quoted string in Bash.
3. Reload your shell configuration
source ~/.bashrc
4. Use your alias
qbstat
It should print output formatted as:
USER PID COMMAND
user1 1234 qbittorrent-nox
⚙️ Optional improvement
If you want to automatically exclude the grep qbittorrent process from showing up, modify the alias like this:
alias qbstat='ps aux | grep qbittorrent | grep -v grep | awk '\''{printf "%-7s %-7s %-20s\n", $1, $2, $12}'\'''
Would you like me to show you a more robust variant that doesn’t rely on grep (e.g., using pgrep or ps -C qbittorrent)? That’s cleaner and safer for scripting.
