What is correct path of bench

i installed bench5.22.3 by pipx in ubuntu23, the path is /home/user/.local/bin/bench, there seems to be a problem when i run bench update in /home/user/.local/bin, command not being executed in bench directory. any suggestions?

The path you are trying to run the command is the location of the bench executable file itself.
bench update should run in a bench instance directory (the directory you created using bench init)

U R right, tks.
