At work I've been moved from ksh to bash per our policy. I haven't configured a .profile or .cshrc before but when I first started the guy that trained me (on just what I need to know in order to do the job) let me copy his .profile, .cshrc, and .cshrc_aliases file so we could all use them and then upload them to each server on which we administer accounts. We've always used ksh as a default so I'm not sure why he had us put a .cshrc file as I believe this pertains to c shell but when i would edit this file it would definitely reflect the change so I just rolled with it.
Now I have to use bash and I just want to get a few tweaks implemented from .cshrc but the syntax appears wrong. For example, in my .cshrc I have one of many if/then statements:
where a.a.a.a and b.b.b.b represent hostnames in our company. I want to login to a devlopment, production, or other environment server and have my prompt reflect that I am in the respective environment. I noticed that in .cshrc the setenv seems to be the equivalent of export in .bashrc but I tried replacing all %s/setenv/export/g and I still received an error when sourcing my .bashrc:
Again - a.a.a.a is a hostname in our company. Is there more to defining those aliases or am I using the export directive incorrectly?
in my .cshrc file, i can set my library files directory like this :
setenv LD_LIBRARY_PATH "/usr/openwin/lib"
now i want to specify my header files directory. please teach how to set it and what/how is the syntax
thank u (1 Reply)

Hi,
I use a specific utility in my .cshrc for setting up the right fonts and I believe it's sufficient to run it once for a whole session.
Since I have sourced it in my .cshrc, it runs every time I do a source of .cshrc or invoke every new terminal.
To resolve this issue, I thought of... (1 Reply)

I was hoping someone could help me with the following query I have please in relation to NX Nomachine.

VDETAPLIB(1) General Commands Manual VDETAPLIB(1)NAME
vdetaplib - Virtual Distributed Ethernet tap emulation library
SYNOPSIS
No synopsis
DESCRIPTION
vdetaplib is a library that emulates tap (tuntap level2 interface, see in kernel sources Documentation/networking/tun.c) and connects tap
virtual interfaces to vde networks.
To use it, the libvdetab.so library must be preloaded (sh, ksh or bash syntax):
export LD_PRELOAD=/usr/lib/vde2/libvdetap.so
(csh, tchs syntax):
setenv LD_PRELOAD /usr/lib/vde2/libvdetap.so
If you want to divert all tap requests to a single vde_switch set the variable VDEALLTAP to the vde socket.
(sh, ksh or bash syntax):
export VDEALLTAP=/tmp/vde.ctl
(csh, tchs syntax):
setenv VDEALLTAP /tmp/vde.ctl
It is possible to set each single interface to different vde_switches by setting the environment variable with the same name of the inter-
face.
(sh, ksh or bash syntax):
export tap0=/tmp/vde.ctl
export tap1=/tmp/myvde.ctl
export ppc=/tmp/ppc.ctl
(csh, tchs syntax):
setenv tap0 /tmp/vde.ctl
setenv tap1 /tmp/myvde.ctl
setenv ppc /tmp/ppc.ctl
It is also possible to specify port, group or mode for a given interface setting environment variables as in the following example.
(sh, ksh or bash syntax):
export tap0_port=5
export tap0_group=vde-net
export tap0_mode=0660
(csh, tchs, syntax):
setenv tap0_port 5
setenv tap0_group vde-net
setenv tap0_mode 0660
The variable to set the specific interface is checked first then VDEALLTAP. VDEALLTAP thus works as a default choice for the vde switch to
be used. If VDEALLTAP is not set and there is no specific environment variable (and for tun -- IFF_TUN interfaces) the kernel provided
interface is used. In this latter case access to /dev/net/tun is required, generally root access.
