I'm setting up Tomcat right now, and I've been directed to create a tomcat_home (catalina_home as of writing) environment variable.
Where is the default location for env variables in Slackware? My current inclination is to create a new script /etc/profile.d/tomcat.sh.
I've just noticed something odd with 'su'. When you run 'su' with both the '-' (aka -l) and -c command options like this: "su -l user -c command" it doesn't appear to run /etc/profile before running the specified command even though the -l option is specified. If you run "su -l user" without the -c it does run /etc/profile.
Now, on other linux such as fedora it works as expected and runs both /etc/profile followed by the command specified on the '-c'. I'm fairly sure it used to work this way on Slackware (and every other UNIX I've ever used) too. "su -l root -c env" is a good way to see, as you'll find most the environment variables are missing.
I am trying to use bash 'printf' to format an environment variable.Doing this I get on the screen just the format I need (underscores mean blank spaces):prompt> printf "%10s" "1.23"________1.23Unfortunately, when this is assigned to a variable, the format disappears:prompt> X=`printf "%10s" "1.23"`prompt> echo $X1.23Does anyone know what can be done in this case to get a proper format?Why does not 'printf' respect the left blank spaces when assigning values to a variable?
View 3 Replies View RelatedI am trying to modify a script for research purposes and am having difficulty here as I have little prior experience with C-shell scripting.
The script looks as follows (it includes tcl commands like runFEP that you can ignore)
#!/bin/bash
for ((old=1, new=2; old<=4; old++,new++))
a1=${old}%50
a2=${new}%50
do
cat > input${new}.conf <<EOF
${a1}

My question: I keep getting a syntax error when defining my two variables a1 and a2. I essentially need these variables to be
a1 = value of variable old divided by 50
a2 = value of variable new divided by 50
Where is the location of the header files for the c++ standard library?
I assume that they were installed by gnu g++, please correct me if i'm wrong.
I'm running ubuntu 10.04 with g++ 4.4.
I looked in /usr/lib/gcc/i486-linux-gnu/4.4/include, but this directory contains only the following:
Code:
Which doesnt seem to include the really basic things like iostream, for example.
Where can I take a look at the header files for these standard c++ libraries?

I am reporting various network statistics in a c++ program by reading the values out of /proc. However, I am having trouble determining the link status. In particular, I am wondering:
1. How are the standard interface flags (IFF_UP, IFF_RUNNING) as referenced in if.h accessed from user land? The ifconfig man page lists its files as
/proc/net/socket (doesn't exist in suse), /proc/net/dev, and /proc/net/if_inet6. None of these seem to contain these flags.
2. ip link show reports a "NO-CARRIER" flag. How does this correlate with the "UP" and/or "RUNNING" flags as reported by ifconfig, and how is it accessed from user space?
I'm about to recompile PHP from source and was planning to download the source code to my Ubuntu machine. Is there a standard place where all the source code goes? I know that PHP has many dependencies and would like to hopefully put it in the right place so as to satisfy as many as possible.
View 6 Replies View RelatedI'm trying to compile Ardour on jessie amd64 using the Debian source code (there's already an ardour package but I want to use different compile options). I've applied the Debian patches and have all the required dependencies installed.
Scons quits with a KeyError message from python2.7 saying that os.environ['DEB_HOST_ARCH_OS'] is not defined.
Checking with 'dpkg-archtecture -l' shows that DEB_HOST_ARCH_OS=linux, but 'print os.environ["DEB_HOST_ARCH_OS"]' in python says that name 'os' is not defined. The scons script has 'import os' at the top so it should be seeing it.
How do I make this visible to python (I'm assuming this problem is specific to the jessie python2.7 installation and not python in general)?

I have installed jdk in my pc, and i've set up the environment variable on the .bashrc file in my home directory although i can use java's compiler and interpreter in terminal (xfce) if i try to use these commands in konsole (kde) for some reason they don't work. do i need to edit other file?
Nevermind, i found out that konsole was being executed with -e $SHELL -l parameters, once i took them out, and just ran konsole everything worked.
I've added an export command to /etc/profile, but the environment variables don't show up when not using a terminal.
For example: when I add:
Code:
To my /etc/profile (then open a new terminal so it registers) and run a graphical program from that terminal, the graphical program can see see the environment variable A.
However if I add the export command to my /etc/profile, then reboot so everything registers, then run that same graphical program from a menu (such as Applications->Accessories->Myprogram), it can't see the environment variable.
What I'm trying to say is basically, my environment variables only show up if I run a program in a shell. Is there a way to set environment variables that will show even without a shell?

I installed debian 8 on a usb drive using this guide. I used a debian 8.2 64-bit image with mate. It has all worked as I wanted it to. However recently I needed to change the PATH variable, and create another environment variable. I have not been able to do neither. What I have tryed (from google):
1. adding "export PATH=$PATH:/xxxx/" to etc/profile or to /home/user/.profile
2. adding ":/xxxx/" to a point in /etc/profile where the PATH variable is set
3. creating a script in /etc/profile.d which run "export PATH=$PATH:/xxxx/"
(where xxxx is the the location i want to add)
I'm newbie on Debian, and I just installed Debian 8.2. (I used to run openSuse, and I see Debian is quite different.)
Where should I set environment variables (like PATH or JAVA_HOME) in order to affect all users?
I read some documentation about that, but It is not clear for me, the difference among "/etc/environment", "/etc/bash.bashrc" and "/etc/profile".
(In openSuse, I used to create a file "/etc/bash.bashrc.local" and set the environment variables there, in order these settings are not lost with updates.)
I've never done much scripting myself and I'm quite unused to the bash as well, but anyway, Here's my problem.
I've a script which is supposed to set some environment variables, using export. However, if I check those variables using echo, they appear not to be set (they are empty). If I set the same variables manually, everything is fine, of course, but I don't want to set them each time manually.
I know many people have asked about environment variables before, but I am having a hard time dealing with these paths while ensuring I don't mess around with the original settings. How would you go about executing these commands in Ubuntu in terms of environment variables?

I am running an application which requires setting environment variables to be set.At the moment, the way I am achieving this is by exporting the EV at the command line, and then running the app from the command line.I want to be able to run the app from my menu (it is already a menu item after I installed it).How may I set the env var so that it is always available, so I can just run the app from the menu instead of from the CLI?

If I create those new variable ( TEC_360_2008=/usr/tec360_2008 ) and update the PATH variable ( export PATH=$PATH:$TEC_360_2008/bin ) then bash detect the command 'tec360' and it runs my program.
