linux - echo 全局替换的解决方案

Question

如何将我所有 ksh 脚本中的 echo 替换为 echo -e。 示例:

输入

包含以下行的脚本，

echo "\nE-MAILING TO INTERESTED PARTIES....\n"
set echo off
echo -e "\nE-MAILING TO INTERESTED PARTIES....\n"

输出:

我不应该打扰 set echo off 命令，只更改打印 echo 命令。如果已经改成了echo -e，我就不应该再替换了。对于根目录中的所有脚本，我应该一次性替换它。

echo -e "\nE-MAILING TO INTERESTED PARTIES....\n"
set echo off
echo -e "\nE-MAILING TO INTERESTED PARTIES....\n"

Answer 1

这应该可行 -

sed 's/^echo "/echo -e "/' filename

测试:

[jaypal:~/Temp] cat tmp
echo "\nE-MAILING TO INTERESTED PARTIES....\n"
set echo off
echo -e "\nE-MAILING TO INTERESTED PARTIES....\n"
[jaypal:~/Temp] sed 's/^echo "/echo -e "/' tmp
echo -e "\nE-MAILING TO INTERESTED PARTIES....\n"
set echo off
echo -e "\nE-MAILING TO INTERESTED PARTIES....\n"

查找 和执行:

find /path/to/directory/ -type f -name "*.ksh" -exec sed -i"bak" 's/^echo "/echo -e "/' {} \;
