How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
sedaccepts;as a command separator. BSDsed(as found on OS X, for example) requires newlines.;can be used to separate most commands in all sed implementations, but cannot be used after certain commands like:,b,},wor#in some implementations. For instanceb a;bis meant to branch to thea;blabel in POSIXseds (that will change in the next POSIX spec version though), and in# foo; bar, that;is part of the comment in all implementations, even GNUsed(same forw file;foo.txt).sed -ne '/CSP/{n;s/./;/3;p;}'should work in allsedimplementations even if IIRC POSIX currently doesn't allow it (a bug in the spec)sedon OS X, actually, since I expected there was some trickery with the semicolon.
