推荐答案
对于有效的unix变量名称,您必须有一种忽略输入无效行的方法. Unix变量遵循以下规则:
You have to have a way to ignore the lines with invalid entry for a valid unix variable name. A unix variable follows this rule:
以下划线或字母开头,后跟0个或多个字母数字或下划线
start with underscore or an alphabet followed by 0 or more alphanumeric or underscore
使用此规则,您可以在BASH中使用此脚本:
Using this rule you can use this script in BASH:
while read k v; do
[[ $k =~ ^[_[:alpha:]][[:alnum:]_]*$ ]] && declare $k="$v"
done < conf.file
这将忽略所有空行或以#或/usr/bin
等开头的行.
This will ignore all the blank lines or lines starting with # or /usr/bin
etc.
在ksh中尝试以下操作:
In ksh try this:
while read k v; do
[[ $k =~ ^[_[:alpha:]][[:alnum:]_]*$ ]] && eval $k="$v"
done < conf.file
