The thing to understand here is that 'and', 'or' and to some extent 'for' in fish are simple commands and fish doesn't track their usage in any particular way (like bash does). You have three choices:
1) Using begin/end to group expressions: if begin test $i = "."; or test $i = ".."; end 2) Using and/or commandness: test $i = "."; if or test $i = ".." 3) Using 'test' command syntax: if test $i = "." -o test $i = ".."; end regards, Maxim On Tue, 25 Aug 2015 08:12:14 +0300, Luciano ES <lucm...@gmail.com> wrote: > Yes, I googled and looked it up in the manual, and still can't solve > this. > > Consider this script: > > #!/usr/bin/env fish > function xlist > for i in (command ls -1a) > echo $i > end > end > > I run it and get 194 items including files and directories.
