shell中$和$@的区别
例子：
复制代码 代码示例:
#!/usr/bin/bash
#site: www.jb200.com
#
E_BADARGS=65
if [ ! -n "$1" ]
then
echo "Usage: `basename $0` argument1 argument2 etc."
exit $E_BADARGS
fi
echo
index=1
for arg in "$*"
do
echo "Arg #$index = $arg"
let "index+=1"
done
echo "Entire arg list as single word."
echo
index=1
for arg in "$@"
do
echo "Arg #$index = $arg"
let "index+=1"
done
echo "Entire arg list as seperated words."
echo
index=1
for arg in $*
do
echo "Arg #$index = $arg"
let "index+=1"
done
echo "Entire arg list as seperated words."
echo
index=1
for arg in $@
do
echo "Arg #$index = $arg"
let "index+=1"
done
echo "Entire arg list as seperated words."
exit 0
执行结果：
复制代码 代码示例:
$ ./test.sh bi yutong
Arg #1 = bi yutong
Entire arg list as single word.
Arg #1 = bi
Arg #2 = yutong
Entire arg list as seperated words.
Arg #1 = bi
Arg #2 = yutong
Entire arg list as seperated words.
Arg #1 = bi
Arg #2 = yutong
Entire arg list as seperated words
以上通过示例，介绍了shell中$和$@的区别，希望对大家有所帮助。
