| − | * Changing Default permissions when creating a new directory
| |
| − | umask u=rwx,g=rwx,o=
| |
| − | * Set default group
| |
| − | newgrp groupname
| |
| − | Remark: this command will start a nested shell. If you want to use the command in a startup script like in .bashrc, to avoid
| |
| − | infinite loop, you should put it in an "if" expression like this:
| |
| − | if [ `id -gn` != "object3d" ]
| |
| − | then
| |
| − | newgrp object3d
| |
| − | exit
| |
| − | fi
| |
| − | * Change default shell
| |
| − | chsh -s /bin/bash haosu
| |
| − | * I/O Redirection
| |
| − | if you want to redirect both standard out and standard error, you can use: 1>out 2>&1, where out is a filename, 1 stands for
