In bash, {a..d} expands to a b c d. Currently this is not happening for me in zsh, and my googling has returned conflicting results.

Some results suggest that {a..d} should work -http://zsh.sourceforge.net/Doc/Release/Expansion.html#Brace-Expansion

The other result I found is from the zsh mailing list which suggests setopt braceccl to get letter ranges using {a-z}. This works, but I'm wondering whether I've misread the Brace-Expansion link, or whether there's something else to consider.

Importantly, I'm using the zsh-grml config, which is probably adjusting a variety of expansion options, but I'm hesistant to start digging through because it's massive, and a cursory grep brace ~/.zshrc doesn't reveal anything.

  • With braceccl you can do {a-d}, without only {abcd}. Form {a..d} doesn't work in any case, at least in my zsh 5.05. It is possible however that something has changed in newest version. – jimmij Jul 29 '15 at 10:20
  • @jimmij {a..d} should work according to the brace-expansion section of the expansion document linked – Squidly Jul 29 '15 at 10:23
  • This document is about zsh 5.0.7, I do not see this paragraph in my zsh manual. It is very likely they added this feature recently, however I cannot see this in the release note: zsh.sourceforge.net/releases.html – jimmij Jul 29 '15 at 10:30

Works fine here with zsh v. 5.0.8
Brace expansion with single characters was added in Jan 20141 so if you're using a version prior to 5.0.6 then it's not available.
