- seq involves the execution of an external command which usually slows things down.paxdiablo– paxdiablo2008-10-04 01:44:41 +00:00Commented Oct 4, 2008 at 1:44
- 16It doesn't involve the execution of an external command for each iteration, just once. If the time to launch one external command is an issue, you're using the wrong language.Mark Baker– Mark Baker2008-10-06 12:57:37 +00:00Commented Oct 6, 2008 at 12:57
- 1So is nesting the only case where this matters? I was wondering if there was a performance difference, or some unknown technical side effect?Sqeaky– Sqeaky2012-01-09 19:07:25 +00:00Commented Jan 9, 2012 at 19:07

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. python-3.x), 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
