更改bash属性文件中密码的所有出现

Question

我想在文件中更改所有密码（要加密），并使用一个命令，并且我坚持使用SED，我不知道该如何告诉它以

我的propeties中的示例 输出。文件就是这样：

someCompanie:
    username: testUsername
    password: testPassword <--- password i want to be encrypted
someOtherCompanie:
    username: testOtherUsername
    password: testOtherPassword <--- password i want to be encrypted

结果就是这样：

someCompanie:
    username: testUsername
    password: a2e48043fcc30e2982ed43fbab01824f1efdaf8eddcc1ac914d1815d7a8738c4 <--- password encrypted
someOtherCompanie:
    username: testOtherUsername
    password: e7c3161f3655662da261015669c3ca449b4c4a738053088b363e83ba93ebdb8f <--- password encrypted

这是我得到的：

grep "password" application.yml | cut -d ":" -f2 | xargs -I pass sed -ie 's,'"$(pass)"',test,g' "app2"

这是我的输出：

sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression
sed: -e expression #1, char 0: no previous regular expression

非常感谢您的关注，

$ cat tst.sh
#!/usr/bin/env bash

encrypt() {
    printf '%s' "$1" | md5sum | cut -d' ' -f1
}

while IFS= read -r line; do
    if [[ "$line" =~ ^([[:space:]]*password:[[:space:]]*)(.*) ]]; then
        line="${BASH_REMATCH[1]}$(encrypt "${BASH_REMATCH[2]}")"
    fi
    printf '%s\n' "$line"
done < "${@:--}"

$ ./tst.sh file
someCompanie:
    username: testUsername
    password: fed3b61b26081849378080b34e693d2e
someOtherCompanie:
    username: testOtherUsername
    password: 7c0453eb71acb77f386b2798767dc97a

用Encrypt（）的内容替换了您要使用的任何加密工具的调用，但要调用它。

使用sed，仅匹配以密码开头的行进行替换。

-i.bak将在保存原始文件时创建文件的备份

$ sed -i.bak '/^password/s/ .*/ newPassword/' input_file
username: testUsername
password: newPassword
