[gentoo-user] Paralell process in Bash
Is there any form to create a child process in a bash-script? I mean... I would like to have a script that use many background process to do some paralell things. I know that I could use after a code block, but, in this way, when I kill the main script, their childs are alive yet. They don't die with their parent. Any form? Thanks -- gentoo-user@gentoo.org mailing list
[gentoo-user] About sed
Hi, I'm learning about the use of the sed command and I have some questions. I'm trying to read in /etc/conf.d/clock the CLOCK variable with: sed '/^CLOCK=*$/p' /etc/conf.d/clock This command, in principe, must print in screen the line that contains CLOCK= in the begin, contains anything between double quotes and ends. Well, this doesn't return anything. If I enter the above command without $, all is ok. But, if I would like to return just that line contains CLOCK=anything and nothing more? For example, CLOCK=anything # set clock of the system and CLOCK=anything are different. Other thing... if i put: sed '/^CLOCK=*/p' /etc/conf.d/clock the return will be anything that contains CLOCK. Why? I suppose that I didn't undestand the use of regular _expression_ metacharacters. So, please, anyone to explain me that? Thanks a lot and sorry by my english...
Re: [gentoo-user] About sed
:) Thanks very much. Now that I read your answear I searched in a book the significant of *,+ and others and I suppose I understood.

What you want is the regexp ^CLOCK=.*$ if you wantanything (including nothing) between the double quotes, or^CLOCK=.+$ if you want something (excluding nothing) between the double quotes.The reason that removing the trailing $ worked is that it matched theCLOCK= part, the * character specifies 0 or more iterates of theprevious character, which is HTH W--Q: Why won't Heisenberg's operators live in the suburbs?A: They don't commute.Sortir en Pantoufles: up 4 days,5:24--gentoo-user@gentoo.org mailing list
Re: [gentoo-user] About sed
For that I understood, this command will return the line of CLOCK= in /etc/conf.f/clock without any comments. Is this right? Well, what I really want is replace just CLOCK=fool1 by CLOCK=fool2 keeping the comments in line. By the way, \1 do really what? If i put \0 the result is the entire line. So, could you explain me this a little more?

Re: [gentoo-user] Strange problem with partition reiserfs
Yes, I'm sure. As a same user I repeated that many times on different partitions and just in that Kate doesn't ask me for a confirmation. Well... With gedit I don't have this problem. gedit ask me for a confirmation. But I would like to use Kate. I suppose that I have to agree about a but in Kate. About the other question. Any answear?

[gentoo-user] Strange problem with partition reiserfs
Hi, I'm with a very strange problem with a partition reiserfs. When I installed gentoo I created a partition to save my personal docs and I formatted it with reiserfs filesystem. Today, I was wrinting a little program in python using Kate and, accidentaly, I overwrite a file on that partition. The strange was that Kate don't ask me for a confirmation about that. Kate just overwrote the file. Well, I imagined that comportament was not right and I tried to ovewrite an archive in the partition mounted under /home and Kate, now, ask me for a confirmation. Strange... any idea? Other thing... I would like to mount that partition such that all files created have the same group and permission. I thought that I could use the umask option, but reiserfs don't have that option, so I don't know how could I do that... Help please... Sorry by my english! Thanks!
[gentoo-user] About --depclean
Hello... i had installed my gentoo there's no many time and i was studing portage and its tools. And now, i have some questions. The use of --depclean would not have erase only the dependences that are not more used for any applicatory one? If yes, why do I need to reconstruct the dependent applications of those dependences that I erased with emerge -- depclean? If no, please, clarify me about the functioning of revdep-rebuild that I did not understand its funcionality. Thanks! Rafael Menezes Barreto = Brazil/PE - UFPE-CIn (rmb3)
Re: [gentoo-user] About --depclean
Ok. I think I undestood. But, why do I need to use revdep-rebuild after emerge --depclean?I mean, emerge --depclean should unmerge just that dependences not necessary anymore by other packages. So, I suppose I don't need to rebuild nothing because I just unmerge dependences unused. i.e.ifI don't have any packagesdependentsof that dependencesunmerged withemerge --depclean, there's no dynamic linkto update. Am I right?Do you undestand what I say? Thanks!
