linux中Shell指令碼所在目錄的絕對路徑

代碼如下	複製代碼
baseDirForScriptSelf=$(cd "$(dirname "$0")"; pwd) echo "full path to currently executed script is : ${baseDirForScriptSelf}" 或者 FULLPATH=$(cd "$(dirname "$0")"; pwd) echo "full path to currently executed script is : ${FULLPATH}" BASEDIR=`dirname $FULLPATH` echo "parent dir is $BASEDIR"

這個功能很給力 直接得到絕對路徑 把指令碼整個目錄及上級目錄全部挪窩的好東西

方法二

代碼如下	複製代碼
#!/bin/sh name=$0 echo "name : $name" dir=$(dirname ${name}) echo "dir  : $dir" path=$(pwd) echo "path : $path" path=${dir/./${path}} echo "path : $path"

執行個體

Shell代碼 

代碼如下	複製代碼
#!/bin/sh  this_dir=`pwd`  dirname $0|grep "^/" >/dev/null  if [ $? -eq 0 ];then                  this_dir=`dirname $0`  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

當路徑中含有小數點時，該方法會有問題。修正方法為加入一個判斷

代碼如下	複製代碼
#!/bin/sh path=$(dirname $0) if [ ${path:0:1} == . ] then path=${path/./$(pwd)} fi
