How to : setting PATH variable for TCL

hii friends , this is a simple problem , but don't mind . plz help me
i had installed tcl.
when i tried to access through commands it is giving error

Code:

$tcl

bash: tcl: command not found

But i had installed it. System path is

Code:

$ whereis tcl

tcl: /usr/lib/tcl /usr/share/tcl

To set path I had tried this command

Code:

# echo "PATH=$PATH: /usr/lib/tcl/" >> ~/.bashrc

Then onwards , when ever Terminal opened, I am getting error as

Code:

bash: /usr/lib/tcl/: is a directory

how to set correct path to tcl ??( what is my error in the command?)
how to remove error message of my wrong path command ??( /usr/lib/tcl/ is a directory )

You need to add this line in .bash_profile or you can add a file .profile and insert this line to this.

Code:

echo "PATH=$PATH:/usr/lib/tcl >> .bash_profile

Remove that from .bashrc and don't leave a space between : and /usr

Hi-

i read where a person did this....

export PATH=/opt/tcltk-8.4/bin:$PATH

it is pointing to bin directory for tcl (whereever that resides on your system).
if you do it this way you will have to type each time you make a new shell i think.

here is the link:
export PATH=/opt/tcltk-8.4/bin:$PATH

it is worth a try anyways. thanks mtdew3q

Code:

linux-kt0w:/home/raju # export PATH=/usr/lib/tcl: $PATH



bash: export: `/usr/bin:/sbin:/home/raju/bin:/usr/local/bin:/usr/sbin:/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/games:/opt/kde3/bin:/usr/lib/jvm/jre/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/home/raju/bin/ns-allinone-2.33/bin:/home/raju/bin/ns-allinone-2.33/tcl8.4.18/unix:/home/raju/bin/ns-allinone-2.33/tk8.4.18/unix:/home/raju/bin/ns-allinone-2.33/ns-2.33/:/home/raju/bin/ns-allinone-2.33/nam-1.13/:/home/raju/bin/ns-allinone-2.33/bin:/home/raju/bin/ns-allinone-2.33/tcl8.4.18/unix:/home/raju/bin/ns-allinone-2.33/tk8.4.18/unix:/home/raju/bin/ns-allinone-2.33/ns-2.33/:/home/raju/bin/ns-allinone-2.33/nam-1.13/': not a valid identifier

Hi -

the link where i got the tip was here:
http://www.damnsmalllinux.org/f/topic-3-23-13180-5.html
export PATH=/opt/tcltk-8.4/bin:$PATH
----------------------------------------------------------------
from another site: http://www.cyberciti.biz/faq/unix-linux-adding-path/
-----------------------------------------------------------------------------------
export PATH=$PATH:/usr/local/bin

BASH / SH shell uses following syntax:
export PATH=$PATH:/path/to/dir1:/path/to/dir2

so for example:
export PATH=$PATH:/opt/ActiveTcl-8.5/bin

looking at these 2 examples from different sites they look kind of identical
and just switched around. I am not an expert but this seems to me like it works.

maybe you are specifying the name of the binary file correctly like
wish8.5 or tclsh8.5 (try using bash maybe)

i might have some links for you if this helped for some cool tcl
stuff that has to do with c++.

for my hobby i am working on other stuff now though mostly java at 3rdshiftcoder.com

i hope some of this helps.
take care -

hi-

i think you put an extra space that you may not want in your export command from
above. i believe it is supposed to run together.

still getting startup error

hey thank you for replying me !
i am still gettin an error message at Terminal startup .

Code:

raju@linux-kt0w:~> 

bash: /usr/lib/tcl/: is a directory

hot to remove this error message ??

I reveal you a secret: there is no executable called tcl. The /usr/lib/tcl and /usr/share/tcl reported by the whereis command are indeed two directories. If you want to interactively run tcl commands, you have to type:

Code:

$ tclsh

%

Hey thank You !!! it's working !!! :) :)

hey that command is working !!
but how to remove that message's . Those message came by my wrong commands

Code:

# echo "PATH=$PATH: /usr/lib/tcl/" >> ~/.bashrc

that is one wrong command i had given. How to remove that message ??

Code:

# echo "PATH=$PATH: /usr/lib/tcl/" >> ~/.bashrc

The >> symbol, as maybe you already know, means "append to". The output of the echo command has been appended as a new line at the end of the file ~/.bashrc. At this point you have to edit this file and delete the unwanted line. In Opensuse you can use kwrite. To launch it from a terminal, just issue:

Code:

kwrite ~/.bashrc

then delete that line, save and close.

yes, i know that . I had allready tried in VI editor. but i haven't found line related to that command. Please once look at my .bashrc file

# Sample .bashrc for SuSE Linux
# Copyright (c) SuSE GmbH Nuernberg

# There are 3 different types of shells in bash: the login shell, normal shell
# and interactive shell. Login shells read ~/.profile and interactive shells
# read ~/.bashrc; in our setup, /etc/profile sources ~/.bashrc - thus all
# settings made here will also take effect in a login shell.
#
# NOTE: It is recommended to make language settings in ~/.profile rather than
# here, since multilingual X sessions would not work properly if LANG is over-
# ridden in every subshell.

# Some applications read the EDITOR variable to determine your favourite text
# editor. So uncomment the line below and enter the editor of your choice :-)
#export EDITOR=/usr/bin/vim
#export EDITOR=/usr/bin/mcedit

# For some news readers it makes sense to specify the NEWSSERVER variable here
#export NEWSSERVER=your.news.server

That 3 path variables ( LD_LIBRARY_PATH,TCL_LIBRARY,PATH ) are the path variables,I had set for Network Simulator 2 software as a part of installation.

Well, the command is quite clear and the line should have been added to .bashrc. Maybe you were logged as root when applying that command? Check the files ~/.bashrc of root and of the users you normally use on this machine.

i am sorry for above , i had n't mentioned that i had edited in root mode.
even i getting message in running as mode only.( i.e. after su command )

Code:

linux-kt0w:/home/raju # vi ~/.bashrc
