获取 sed 错误 [英] Getting sed error

问题描述

我是 shell 脚本的新手，但遇到此错误并且无法弄清楚发生了什么.

I'm new to shell scripting but getting this error and cant figure out what up.

sed: 1: "/Users/local/Do ...": extra characters at the end of d command
sed: 1: "/Users/local/Do ...": extra characters at the end of d command
sed: 1: "/Users/local/Do ...": extra characters at the end of d command
sed: 1: "/Users/local/Do ...": extra characters at the end of d command

这是我正在运行的脚本

for fl in $(S_convertPath ${RESOURCE_DIR}/db)/db.changelog-*xml; do
    sed -i "s/HOSTNAME/${IP_ADDRESS}/g" $fl
done

谢谢

推荐答案

鉴于 sed 似乎认为您正在运行 delete line 命令 (d)，您可能希望输出命令以查看在您的环境变量中的实际内容:

Given that sed seems to think you're running a delete line command (d), you may want to output the command to see what's actually in that environment variable of yours:

for fl in $(S_convertPath ${RESOURCE_DIR}/db)/db.changelog-*xml; do
    echo sed -i "s/HOSTNAME/${PSM_SERVER_ADDRESS}/g" $fl
done

PSM_SERVER_ADDRESS 很有可能会破坏您的 sed 命令(并且可能需要对其进行处理以使其干净).执行此操作的一种方法(前提是您有足够新的 sed)是使用未出现在环境变量中的分隔符，例如:

There's a good chance the PSM_SERVER_ADDRESS is corrupting your sed command (and may need to be processed to make it clean). One way to do this (provided you have a recent enough sed) would be to use delimiters that do not appear in the environment variable, for example:

sed -i "s?HOSTNAME?${PSM_SERVER_ADDRESS}?g" $fl

既然您已经接受了这个答案，我不妨为您发现的其他问题添加解决方案.似乎 BSD sed 与 Linux 不同，它有一个要求，即您提供对 -i 选项的扩展.因此，虽然 Linux 允许:

Since you've accepted this answer, I may as well add the resolution for the additional problem you found. It appears that BSD sed, unlike Linux, has a requirement that you provide an extension to the -i option. So, while Linux allows:

sed -i "sed-command"

要就地编辑，BSD 变体需要:

to edit in-place, the BSD variant needs to have:

sed -i "" "sed-command"

带有空的备份后缀.

否则，sed 可能会使用您的命令作为扩展名，并使用您的第一个文件名作为命令.

Without that, sed may use your command as the extension and your first file name as the command.
