Background

Recently I need to run my code on a server, but default bash is hard to use

Contents

Versions of shell are stored in \etc\shells

• A user can change their own shell to any thing: which, however must be listed in the /etc/shells file.
• Only root can run a shell not listed in /etc/shells file.
• If an account has a restricted login shell, then only root can change that user’s shell.

Check /etc/passwd can find account information for each user.

# change the shell in /etc/passwd to bash just like modify the /etc/passwd
usermod --shell /bin/bash user
# or
chsh --shell /bin/sh user
chsh -s /bin/sh user
