如何刪除我的文件中的字元串？

如何刪除或刪除字元串。所以基本上我想刪除下面的整個字元串

[MTT-5634](https://my.atlassian.net/browse/MTT-5634)

我努力了

sed -e 's/\[(MTT|MCC)-[0-9]{3,4}\?]\?://g;s!.\?http[s]\?://\S*!!g' input.txt > output.txt

輸出

[MTT-5634]

When you didn't enable the -Extended regex, so you will need to escapes a few special character such as (, ), |, {, }, ?. you also have a trailing :in your first sed statement that should be removed. Also you forgot to escape the closing bracket]`.

your own corrected (but not improved) command should be:

sed -e 's/\[\(MTT\|MCC\)-[0-9]\{3,4\}\?\]\?//g;s!.\?http[s]\?://\S*!!g' infile
