The absolute path of the directory where the shell script resides in Linux

The code is as follows	Copy Code
basedirforscriptself=$ (CD "$ (dirname" $) "; pwd) echo "full path to currently executed script is: ${basedirforscriptself}" Or fullpath=$ (CD "$ (dirname" $) "; pwd) echo "full path to currently executed script is: ${fullpath}" Basedir= ' DirName $FULLPATH ' echo "Parent dir is $BASEDIR"

This feature is very powerful to directly get the absolute path to the script entire directory and the superior directory all Novo Good Things

Method Two

The code is as follows	Copy Code
#!/bin/sh Name=$0 echo "Name: $name" dir=$ (dirname ${name}) echo "dir: $dir" path=$ (PWD) echo "Path: $path" Path=${dir/./${path}} echo "Path: $path"

Instance

Shell Code

The code is as follows	Copy Code
#!/bin/sh This_dir= ' pwd ' DirName $0|grep "^/" >/dev/null If [$?-eq 0];then This_dir= ' DirName $ ' Else DirName $0|grep "^." >/dev/null Retval=$? If [$retval-eq 0];then This_dir= ' dirname $0|sed ' s#^.# $this _dir# ' Else This_dir= ' dirname $0|sed ' s#^# $this _dir/# ' Fi Fi Echo $this _dir

This method can be problematic when the path contains a decimal point. Correction method for adding a judgment

The code is as follows	Copy Code
#!/bin/sh path=$ (DirName $) if [${path:0:1} = =.] Then path=${path/./$ (PWD)} Fi
