Shell Programming and Scripting

Hi frnds!
i m installing a software named 'Gamit' by using bash.
bt i recieved the follwoing error:

.. removing any existing Makefiles or archive files from libraries directories
/root/Documents/ISP/Gamit_10.4/com/rmfresh: Permission denied.

.. removing any existing Makefiles or archive files from gamit directories
/root/Documents/ISP/Gamit_10.4/com/rmfresh: Permission denied.

.. making libraries and gamit
/root/Documents/ISP/Gamit_10.4/com/make_gamit: Permission denied.
Failure in make_gamit -- install_software terminated


while i have made sure that all the files are in their respective directories where they should be!
bt i guess i dont have permission to execute it!
then i reviewed the instruction and found a particular instruction given on shell and that was ,

To execute GAMIT and GLOBK you will need to set your login path to
include /root/Documents/ISP/Gamit_10.4/com /root/Documents/ISP/Gamit_10.4/gamit/bin /root/Documents/ISP/Gamit_10.4/kf/bin


after that i tried to change my login path by applying this
export PATH=include
export PATH=/root/Documents/ISP/Gamit_10.4/com
export PATH=/root/Documents/ISP/Gamit_10.4/gamit/bin
export PATH=/root/Documents/ISP/Gamit_10.4/kf/bin

and all of them are accepted !
bt then "sudo" command is not getting accepted by the shell!!

After changing the path when i give Sudo or chmod command then this happens:




SUSE1:~/Documents/ISP/Gamit_10.4 # chmod 755 install_software
If 'chmod' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf chmod




INfact it is not accepting any of the command like
ls
dir
or
cnf itself
when i give 'cnf' commanbds it says ,
If 'cnf' is not atype you can use command-not-found to lookup the [ackage that contains it, like this:
cnf cnf





while i m already log in from 'root'


Kindly HELP me out from this!

I have changed the read/write/execute permission to that file on which permission was denied!
and it executed bt later on!
It give same error to another file! i know by giving chmod it will work to!
bt can anyone tell me that how can i apply chmod to all the files in the directory?

NOW acing thiis error!

GAMIT and GLOBK to be installed into /root/Documents/ISP/Gamit_10.4

If you need help with command line options type CTL_C now and type
install_software -help on the command line

The compressed tarfiles will be removed after extraction of the
directories, but except for that, the script may be stopped and
rerun safely from any point. Tarfiles to be uncompressed:

ls: No match.


Continue ? (y/n)


.. uncompressing and extracting the directories:


.. adding /root/Documents/ISP/Gamit_10.4/com to your search path to continue installation


To execute GAMIT and GLOBK you will need to set your login path to
include /root/Documents/ISP/Gamit_10.4/com /root/Documents/ISP/Gamit_10.4/gamit/bin /root/Documents/ISP/Gamit_10.4/kf/bin

You will also need the alias or link gg --> /root/Documents/ISP/Gamit_10.4


Your Operating System type is: Linux
Your default awk version is: /usr/bin/awk

Searching directories set in libraries/Makefile.config for X11 installation
Verified these paths to X11 libs and includes
X11LIBPATH:
X11INCPATH: /usr/include

Are these paths complete and correct for your system? (y/n)

X11LIBPATH and X11INCPATH OK in libraries/Makefile.config.

GAMIT dimensions in /libraries/Makefile.config are set to
maxsit = 60
maxepc = 2880
maxatm = 13
maxsat = 32

Are these defaults found in Makefile.config correct?
If NOT edit the Makefile.config now before choosing to contine
Continue ? (y/n)

Your system path variable "PATH" has changed by you completely.
Common path are /usr/local/bin:/bin:/usr/bin:/sbin:/usr/sbin:.
To add new path into PATH variable use.

Code:

 
export PATH=$PATH:/new/path
