Re: [gentoo-user] Re: extend a running shell command
Hi ng, first of all thanks for the discussion. I'm think that there is no build-in function in bash, now. I thougth there could be an key-combination to handle that, like the ctrlz (of course you do not need alt). Moreover I think this could really be a security issue. The trick with the shell script could work of course, but it is not so nifty I thougth it would be. ;-) To extend a running command, we have found some solutions that are working I think. But to edit an entered command line is tricky and not trivial. The only solution I see is to extend the shell functionallity. Maybe there is an other shell that have this bug/feature, but don't know one. THX /CrPy -- [EMAIL PROTECTED] mailing list
[gentoo-user] Re: extend a running shell command
Hi ng, sorry, but I think you don't get the problem. Type sleep 100h Enter in your shell. And now don't kill it or stop it. Now imagine that you actually forgot what you really wanted: To halt the machine after the program (that already runs and may be it will need to run for some hours because it is a compile process or similar). And imagine that you don't want to sit all the time behind your computer and wait until the program finishes to be able to halt the computer. So, what I want is, to append to the aready running command line a new command without stopping the old (because then it would have to start it from the beginning). I think, it would be ok to suspend the running program temporarily and to resume it after a short time where I append the additional command to it. After all it should look like i never executed sleep 100h but sleep 100h; halt One solution I have is to suspend the command with ctrlaltz and type fg; halt But what if I have a longer queue of commands and I like to edit the command line. e.g. make clean make dep make bzImage make module make modules_install And now I see that I have a typo in the line (the make module - make modules). How can I change the entered command line while excuting this command line? Sorry, it was not easy for me to explain it in a way that somebody else could understand it. Maybe it is more clear now.

Re: [gentoo-user] Re: extend a running shell command
Take a look at my example, I think the only way is to either add commands into the shell itself (the core code of it) as some sort of free linking nodes. Currently theirs no capacity, that I've ever seen to edit the command line while its running. It could be dangerous too, since some programs depend on knowing the commandline. Although in your situation, it would seem safe enough. On Wed, 2003-06-18 at 19:01, CrPy wrote: Hi ng, sorry, but I think you don't get the problem. Type sleep 100h Enter in your shell.

THX /CrPy -- [EMAIL PROTECTED] mailing list If I understand correctly, all you have to do is type the command. The terminal will still accept input and should run the command after the first has run. If you do notice an error (as in your example), the command will terminate where ever you had your typo. So in your example, just type in the rest of your command again properly starting with: make modules make modules_install Then, when the first part terminates with the error, the next section will proceed. It is however some times difficult to type if you have output from your job/process spilling on your screen. The shell is still capturing your characters however.
