问题描述
-test1:
name: test1
description: this is test1
label: label1 label2
-test2:
name: test2
description: this is test2
label: label3 label2
-test3:
name: test3
description: this is test3
label: label3 label1
在我的shell脚本中,我想实现两个目标
例如:如果输入参数为“ lable1”,则函数应返回[test1,test3] :如果输入参数为“ lable2”,则函数应返回[test1,test2]
例如:如果输入参数为“ test1”,则函数应返回:
-test1:
name: test1
description: this is test1
label: label1 label2
解决方法
这是一种轻松的方式。也许您可以对其进行改进或使其更适合您想做的事情。在此示例中,我们将两个函数放在相同的位置,结果取决于arg。您可以通过放置自己的正则表达式对其进行修改。
#!/bin/bash
function search {
searcha=$1
if [[ ${searcha} =~ test ]]; then
searcht=true #the arg is a test
else
searcht=false #the arg is a label
fi
test=""
name=""
desc=""
label=""
i=0
while IFS= read -r line
do
if [[ $i == 0 ]] ; then
[[ ${line} =~ ^-.*:$ ]] && test=${line} && i=1
elif [[ $i == 1 ]]; then
[[ ${line} =~ name: ]] && name=${line} && i=2
elif [[ $i == 2 ]]; then
[[ ${line} =~ description: ]] && desc=${line} && i=3
elif [[ $i == 3 ]]; then
[[ ${line} =~ label: ]] && label=${line} && i=4
fi
if [[ $i == 4 ]]; then
if $searcht; then
if [[ $test =~ $searcha ]]; then
echo $test
echo $name
echo $desc
echo $label
return 0
fi
else
if [[ $label =~ $searcha ]]; then
echo ${test:1:${#test} -2}
fi
fi
i=0
fi
done < manifest.yaml
}
result=$(search $1)
for ix in ${!result[*]}
do
printf "%s\n" "${result[$ix]}"
done
