View 1 Replies View RelatedGeneral :: Which Environment Variables Not Inherited By Bash Shells
Jan 2, 2011I am using Linux some years, but since I built a LFS, I feel noobish again. Now with the help of BLFS I am setting up my environment and somewhere I incidentally read, that not every variable is inherited by a child Bash shell. As for the $PS1 and $PS2 variables I know, that they are not inherited by non-interactive Bash shells (and there is no reason why they should in my opinion). Well, as for my first thread I hope the title gives enough information on what I want to know. But anyways: Which environment variables are not inherited by Bash shells?

for instance you changed the source code then you ran ./configure then make then make install ....etc you checked the software and it functioned as you expected it does , now you want to remove all the makefiles and all that other jizz that you don't need or want anymore in the source (obviously in order to package it for distribution)

General :: Calling A Script And Giving It A Variable?
Apr 22, 2011I have a script1.sh (see code below) which calls another script (which is a sort of template -> template.sh). But when i call template.sh i need to send an argument with it.

#!/bin/sh
VAR=`./template.sh -d $dirpath`
exitstatus=`echo $VAR`

echo "$VAR files which are older than 1 hour in folder $dirpath" exit $exitstatus I geuss the command should look like something like this command

You don't have to look at the code of template.sh, thats not important. I just need to know how i get this to work I don't think it's that hard, but i just can't see it ...

2. normal build
3. Copy Images
4. Arch
User manually has to input ans for these questions:-

yes

The ans's are fixed and this won't change. How shall i hard-code them or do something in the script so as when script flow reaches to this point it automatically take's these value. So far the cron job is not getting completed as it's waiting for user to key in these values manually. I had faced similar issue while building kernel modules but there it was easier as i had to take default values always:-

General :: Calling Gurus And Noobs - Review Filesystem Hierarchy Explanation?
Jun 10, 2010Back when I was first learning Linux, one of the questions that I kept wondering about was "what are all these files and directories for?" I couldn't find a resource that would explain them in a digestible manner. Specifically, I was looking for one that would allow me to look at a Linux filesystem interactively, collapsing and expanding folders to look at just the ones I was interested in at the moment. So later, when I got the opportunity, I wrote it.
But despite a ton of research, I'm still not totally knowledgeable on the subject. The most important thing I'm looking for right now is for experienced Linux/Unix people to tell me where I got stuff wrong, and for newbies to tell me how useful it is to them and which things need clarification. I'm also interested in technical and graphical ways to improve usability, like better icons, layout, etc. I know I need to be able to collapse long descriptions, but what would you like to see? The Works Cited list and a full introduction are still on the way as of this writing.
Without further ado: Linux Filesystem Hierarchy Explanation. You'll need a fairly recent browser that can handle XSLT; the actual info is stored as XML, and transformed into HTML with an XSLT stylesheet. This is still a work in progress, and I'll be updating it as the thread progresses.
Finally, would people be interested in collaborating with me on this, as an open-source project? I've never done anything like that, and I'm not sure how much time I'll be able to give it in the future, but I really think this should be continued and expanded.
Edit: Works Cited and decent intro are now in place.

View 2 Replies View RelatedSlackware :: How Are Variables Set For Interactive Shells
May 5, 2010I am trying to figure out where variables are set for interactive shells? In particular, I am trying to have LS_OPTIONS inherited by interactive shells as it is by login shells. I understand LS_OPTIONS is set in /etc/profile, and this may not be processed by interactive shells but by login shells. However, I also note other variables such as PATH and INPUTRC are set correctly in interactive shells, and these are also set in /etc/profile from what I understand. So how is it determined which variables are inherited by all shells, and which are just for login shells?
View 16 Replies View RelatedSlackware :: Read $PS1 On Non-login Shells?
Jun 6, 2010Let's say that I have a customized Bash prompt stored as a PS1 variable. My variable gets read every time I invoke a login shell, i.e., when logging in in one of the standard virtual terminal or by invoking xterm with the -ls parameter.
However, when I just invoke the terminal without specifying that it is a login shell, I just get something like: bash-XXX$ as a prompt.
where should I place my PS1 variable so that it could get read even on non-login shells?
Programming :: Different Initialized Environments For Shells Vs Emacs?
Aug 7, 2010I'm finalizing the the dual-boot addition that I recently completed. I've added lubuntu to the LT3114u Netbook that I use. That's done, now I'm migrating my user environment back from the Cygwin one that I've been using on Windoze, as of late. One of features that's been useful has been the global environment management possible with the windoze UI functions. As I coded my emacs environment while 'over there' (windoze side), I included a check for the lisp library repository path environment variable EMACSLOADPATH. It is globally available when one logs in, and does not get set in any user scripts, or dot files any to do with CYGWIN or emacs.
While it has been easy enough to set EMACSLOADPATH for the login shell environment, via .bashrc, .profile, and system wide via /etc/profile, I have not been able to have '/usr/bin/emacs23' have EMACSLOADPATH set when invoked via the LXDE UI. Thus, it would appear that emacs is not being initialized with the same environment that any of the shells are (old school?). Thus, what is it that one must update in order to have GNU emacs initialized with the same environment variables as bash? Or, put another way, why aren't the environment variable defined in /etc/profile, ~/.bashrc and/or ~/.profile ending up in the initialized environment upon invocation of emacs23 on lubuntu Linux?

Slackware :: Difference Between Login And Interactive Shells
Apr 22, 2010I am having trouble distinguishing between login and interactive shells as they relate to terminals. I understand that a login shell is what is started when you login, and an interactive shell is used by scripts and such. I also get that terminals will use an interactive shell by default. What I don't understand is why interactive shells have no prompt by default. Is their a way to get an interactive shell to inherit the normal PS1 prompt? Is it considered bad to do this? Would it be better to have terminals start login shells, and if so why or why not?

Ubuntu :: Retrieve Panels Firefox Shells On Dual Boot
May 13, 2011i am running ubuntu 10.10 on an aspire 5734z laptop, as 11.04 has a backlight issue, and i am dual booting with win7, which i am currently on. i have/had KDE, xfce, desktop edition ubuntu, and gnome 3 sessions installed. i had noticed recently that startup is taking longer than usual, 2x the time as win7, ubuntu and windows are both 32 bit bytheway. after grub, it would be a black screen with only '_' displayed, followed by a screen that says something about sql stuff. i figured this could be the reason my startups were long, and as i dont use sql (that i know of) i decided to just remove it and hope that would fix the problem... yeah, im a linux-noob. i went to software center, searched for it and removed the first entry, and it said it would remove some other stuff, mostly sql named things, plus shotwell and evolution, which i also dont use. after it went thru applying changes, i selected the next one on the list for removal, and the software center froze.
i logged out of the gnome3 part, and logged into ubuntu desktop edition. i then only saw a wallpaper, both of the default panels were gone. at this point i decided a reset was in order. i logged back into the default ubuntu desktop edition part, and the panels were still missing. i figured i would login to gnome3 or kde and see if i could get something figured out from there, but they are missing from the drop down box. the only ones remaining are ubuntu (desktop, recovery and safemode) and xcfe. i logged into xcfe only to find out firefox is gone. i am not familiar with xcfe, i only added it to maybe use sometime when i need to extend battery time, and with no click here to get online - icon in the panel, i figured my best bet was to return to windows and plead for help, before i tried to 'fix' something else, and made an even bigger mess. i dont know what i couldve done to basically render my ubuntu useless to me, to get rid of my panels, firefox, and i dont even know what else.. but the only thing i did at all was to remove the top sql entry, which was something like sql3_lib or something like that.
