* Porting an alias from bash to zsh fails. @ 2004-10-23 21:52 s. keeling [not found] ` <m3mzyd6pzp.fsf@asfast.com> 0 siblings, 1 reply; 7+ messages in thread From: s. keeling @ 2004-10-23 21:52 UTC (permalink / raw) To: zsh-users Hi list. I'm new to zsh so this could well be pretty simple. I've been wondering why the following works in bash, but fails miserably in zsh. I've tried stuffing the font into an ENV variable, I've replaced the double quotes with single ticks, I've inserted a "\" before the embedded space char, and I've used the real font name (not the ENV var) in the alias itself, all to no avail. What am I missing here?

It's almost certainly because the default setting of the NO_MATCH option is reversed in the two shells. In bash, by default, when a glob doesn't match anything, the pattern is left unexpanded, but in zsh by default it generates the "no matches" error. > What am I missing here? > RXVTNEWSFONT='-*-neep alt-medium-*-normal-*-*-100-75-75-c-*-iso8859-1' > > alias dfn="rxvt +sb -fn $RXVTNEWSFONT -geometry 128x51+69+42 \ > -e nice /usr/bin/slrn -f /home/keeling/.jnewsrc-dfn \ > -h news.individual.net" This one would have worked for you if only you'd put the entire thing in single quotes instead of double quotes. There's no reason to expand the variable at the time the alias is defined; let it be expanded (and thus not globbed) at the time the alias is _used_. This has the added benefit that you can change the value of the variable to change the font used by the alias, without having to redefine the alias again.

Thanks. Your excellent explanation has > solved it for me. Much appreciated. Lloyd's suggestion works in this case, but it would fail in the event that the value of the variable contained any single-quote characters. A better solution would be to swap the single and double quotes: alias dfn='rxvt +sb -fn "$RXVTNEWSFONT" -geometry 128x51+69+42 ...' ^ permalink raw reply [flat|nested] 7+ messages in thread

Well, as you probably know, that's another of the suggestions that I made (see the bottom part of my original reply in this thread). -- Lloyd Zusman ljz@asfast.com God bless you. ^ permalink raw reply [flat|nested] 7+ messages in thread

There's no reason to expand the This is better. Specifically, when I type "alias", I see: dfn='rxvt +sb -fn "$RXVTNEWSFONT" -geometry 128x51+69+42 \ -e nice /usr/bin/slrn -f /home/keeling/.jnewsrc-dfn \ -h news.individual.net' [s/\\$//g] ... instead of seeing the _expanded_ version of $RXVTNEWSFONT in there. Thanks. Much appreciated. -------------------- Perhaps I should start a new thread here, but should I assign any significance to the fact that bash =~ 0.51 Mb and zsh =~ 0.4 Mb? Specifically: dpkg -l zsh ii zsh 4.0.4-33 A shell with lots of features. If it's got "lots of features" (presumably, > bash), why's it smaller? More efficient coding, or does zsh throw out extraneous stuff that bash cares about? -- Any technology distinguishable from magic is insufficiently advanced.

Thanks. I was unaware of those. So much stuff to read when you start playing with a new toy. :-) -- Any technology distinguishable from magic is insufficiently advanced.
