For all of you C-shell fans - heres a couple of bugs/puzzles. (I don't know the answer to the second.) The following alias should give a directory listing of the files which have a specified pattern in the middle. It only works if the pattern is at the end. alias lm 'ls -l *\!**' Its easy to make it work, but I think that the above is acceptable. The next has to do with how do you run a command which has nested command substitutions? From what I can see, you cannot. I would love to be able to type (in a more complicated shell script and using any amount of quoting necessary) echo `echo `date`` but no amount of quoting seems to satisfy the shell. Any ideas? (I know - RTFM, but I have grepped sh and csh for nest, recurs, ... and have come up empty.) Any suggestions would be appreciated. Both problems exist on Suns and Ultrix 1.0.

It is not clear to me that either is a bug. Perhaps it would be easier to address any questions if you indicated what you really wanted to do. For example, using the eval "command" (as in "echo `eval date`") might do what you want, but since you really didn't say... -- Fred @ DEC Ultrix Applications Center {decvax,seismo,cbosgd}!decuac!avolio

Here's another good C shell quirk: $ echo foo foo $ repeat 3 echo foo foo foo foo $ repeat 3 repeat 3 echo foo foo foo foo foo foo $ repeat $N repeat $M echo foo # $N and $M are integers [ $N + $M - 1 foo's ] $ repeat $N1 repeat $N2 ... repeat $Nk echo foo [ $N1 + $N2 + ... + $Nk - k + 1 foo's ] $ Tim Smith ihnp4!cithep!tim ima!ism780!tim
