ubuntu shell編程中載入函數或者變量的方法

shell編程中調用別的文件定義的函數或者變量的方法

#!/bin/sh

if [ -r backfunc ] ; then
. /home/fef/shell/backfunc  #"."後面有個空格，並且backfunc必須使用絕對路徑！!
else
	echo "`basename $0` cannot locate backfunc file"
fi

echo -n "Enter the code name: "
if [ "$CODE" != "$_CODE" ] ; then
	echo "Wrong code... exiting... will use default"
	exit 1
fi

echo "The environment config file reports"
echo "FULL backup Required	: $_FULLBACKUP"
echo "$LOGFILE"

其中backfunc文件內容如下：

#!/bin/sh

# name: backfunc
# config file that holds the defaults for the archive systems
_CODE="comet"
_FULLBACKUP="yes"
_LOGFILE="/logs/backup"
_DEVICE="/dev/rmt/On"
_INFORM="yes"
_PRINT_STATS="yes"

最後運行上面的腳本$:sh readfunc comet

得到的結果：

The environment config file reports
FULL backup Required : yes
