The bash completion provided with git doesn't escape or quote parens in tag or branch names. Alternatively, it doesn't reject branch or tag names with parenthesis as an invalid name (as it does for names with spaces or tabs) Bash treats parentheses in unquoted words as a word separator. When encountering this problem I was using git version 2.2.2 and bash version 4.3.11 Steps to reproduce with bash: mkdir foo cd foo git init foo touch bar git add bar git commit -m "Went to a bar" Then for tags git tag 'v1.0.0(215)' Or branches git branch 'mybranch(myuser)' And the actual bash completion git checkout # Use completion here -- it won't escape the parenthesis git checkout master git branch -d # Use completion here -- it won't escape the parenthesis Similarily, when typing a name with an escape character such as "mytag\(", it won't complete the name from that point. This appears to be true for other bash meta characters as well such as '<', '>', '|', ';', '&' ----------- Kevin Stenerson kevin@xxxxxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
