[英]Change directory permanently in a bash script
I'm trying to change directory in a called bash script. 我正在尝试在一个称为bash脚本中更改目录。 For this I tried to use
cd
command. 为此,我尝试使用
cd
命令。 But after the script ends current directory is restoring to position before the script call. 但是在脚本结束之后,当前目录将还原到脚本调用之前的位置。 I also tried to change
PATH
variable but it didn't show any effect too. 我也尝试更改
PATH
变量,但也没有显示任何效果。 Is there a way to do this? 有没有办法做到这一点?
When you execute a shell script a new shell is started for execution of this script. 当您执行Shell脚本时,将启动一个新的Shell以执行此脚本。 This shell won't affect its parent processes.
此外壳程序不会影响其父进程。
To execute a script in your current shell's context use the source
or .
要在当前shell的上下文中执行脚本,请使用
source
或.
commands: 命令:
. cd.sh
source cd.sh
