Example 1.

The new test.sh content under/home/admin/test/is as follows:

CD 'dirname $0echo 'pwd'

Then return to/home/admin/to execute

sh test/test. SH

Operation Result:

/home/admin/test

This allows you to know the location of the files deployed with the script, as long as you know the relative location can be based on this directory to locate, and can not care about the absolute location. This increases the portability of the script and can be executed on any server, if it is a deployment script.

DirName used to fetch the directory where the specified path resides

$ A indicates the currently running command

Example 2.

Create a new env.sh,coltaskmanager.sh under ~/server/colline/cluster5_2/bin, and then invoke the script in coltaskmanager.sh env.sh

At this time, we can achieve this:

. 'dirname $0'/env. SH
