nlines=6
index=0
iplist=
while read line
do
index=$[ ${index}+1 ]
iplist[$index]="$line"
done < `sed -n "5,${nlines}p" "cloudfs_deploy.conf"`
echo ${iplist[@]}
运行这段脚本之后,总是在sed那行报ambiguous redirect错误
conf文件存在,有6行,我单独运行nlines=6 ; sed -n "5,${nlines}p" "cloudfs_deploy.conf"
是没有错误的
求教这是什么原因?

因為第六行你使用了奇怪的語法。顯然你想要的是:
bash
nlines=6 index=0 iplist= sed -n "5,${nlines}p" "cloudfs_deploy.conf" | while read line; do index=$[ ${index}+1 ] iplist[$index]="$line" done echo ${iplist[@]}
