Such symlinks should not be added: Many shells have similar builtins, so which shell's man page would you link? To see the problem, look at alias(1). No, the alias builtin is not csh(1)-specific, ksh(1) has an alias builtin, too. Also, some shell builtins have the same name and similar functionality as stand-alone commands, for example echo(1), test(1). There are exceptions to the rule. For example, cd(1) is a shell builtin, but not a stand-alone command. On the other hand, not having symlinks for builtins makes it a bit harder to find manual information about them. But that's less annoying than a large number of symlinks, pointing mostly at the man page of the shell you are _not_ using. Thus, whenever you discover some unknown command (for example, suspend), try the following commands: $ apropos suspend # see man(1) $ which suspend # see which(1) $ alias suspend # see ksh(1) alias builtin $ man ksh # or whatever shell you are using Search the shell man page in order to find out whether it's a shell builtin or a default shell command alias. > I type suspend at the cmd line, it drops me past the command line. > Can't ^C or ^Z or anything out of it. Does it have a purpose? Try this: [EMAIL PROTECTED] $ echo $$ 22151 [EMAIL PROTECTED] $ sudo -i [EMAIL PROTECTED] # echo $$ 32319 [EMAIL PROTECTED] # suspend [1] + Suspended (signal) sudo -i [EMAIL PROTECTED] $ echo $$ 22151 [EMAIL PROTECTED] $ exit You have stopped jobs [EMAIL PROTECTED] $ fg %1 sudo -i [EMAIL PROTECTED] # echo $$ 32319 [EMAIL PROTECTED] # exit [EMAIL PROTECTED] $ echo $$ 22151 [EMAIL PROTECTED] $ exit Yours, Ingo
