First, to "overwrite" any file, just save a document with the same filename. Working in a GUI, you'll typically be prompted to confirm you want to do this. In a terminal, use "mv"

Second, the /etc directory should not be in your /home directory----perhaps you mean that you want to replace a file in /etc with one in /home??

sudo mv ~/newfile /etc/oldfile

where newfile is the name of the file in your home directory and old file is the name of the file in the /etc directory

Just my opinion, if you do not know how to copy/move a file to /etc, you should not be messing with files in there.

Fedora does not use sudo by default, unless specifically installed by the user.

whoops, you're right. I forgot, it's been a while since I used fedora.

sajjadpu, you are going to have to have root privlidges.

while I don't entirely agree with towheedm, His caution is reasonable. You could do a good amount of damage to your system if you are mistakenly overwriting something you shouldn't
On the other hand you are never going to learn to swim if you don't get your feet wet.

what exactly are you replacing? replacing files in etc is not typical.

hi dear.currently i installed fedora 16 on core I3 desktop. after it i was
interested to install xmgrace on it. i installed the following files

fftw2-2.1.5-22.fc15.i686
libpng10-1.0.56-1.fc16.i686
libXp-1.0.0-16.fc15.i686
fftw-3.3-3.fc16.i686
pdflib-lite-7.0.5-1.fc16.i686
grace-5.1.22-9.fc16.i686

then the next step was to replace id.so.comf file having the text

include ld.so.conf.d/*.conf
/usr/kerberos/lib
/usr/X11R6/lib
/usr/lib/sane
/usr/lib/qt-3.1/lib
/usr/local/lib

in it. the name of old file is also ld.so.conf. the new ld.so.conf file is necessary to overwrite so that xmgrace can start. if you know another method of installing xmgrace then it will give me highly pleasure. thank you very much.

Was this installed via yum? Modifying your ld.so.conf file can have serious effect on other apps.

Just installed it on Fedora 14 and it ran without any manual intervention.

you do not replace that file

you run "ldconfig" on the new software ( you BUILT FROM SOURCE )
for rpm's and yum there is NO NEED

also you NEED to be root to do that to the SORRCE BUILT FILES -- NOT the rpm's
see the manual and help page

Code:

su -
ldconfig --help
--- and ----
man ldconfig

and HOW did you install

fftw2-2.1.5-22.fc15.i686

fftw-3.3-3.fc16.i686
pdflib-lite-7.0.5-1.fc16.i686
grace-5.1.22-9.fc16.i686

this way ? or some other ?

Code:

yum install fftw libpng10 libXp grace

and why dose one program need both
the old fft2 AND the current fft3

what is it you are installing ?
and what instructions are you using ? xmgrace ?

see the other thread
"problem to install xmgrace on fedora 16 "
https://www.linuxquestions.org/quest...a-16-a-941617/

Please post
The instructions are you using ?
where you cot them
and what it is you are trying to do .

Please read the previous posts carefully concerning ld.so.conf.

What was the EXACT error(s)? Could you please post the complete output from:

Code:

su -c "yum install grace"

so you DID NOT use the RECOMMENDED program "yum" to install prebuilt programs

from the above i am guessing you "double-clicked" on random rpms you just downloaded from some random site
-- if so , not good

to repeat my self ...
WHAT instructions ( if any) are you trying to fallow !
and from WHERE ( a url link please) did you find it ?

Quote:

we can not help if we do not know just WHAT you did
please post the EXACT commands you tried

it is VERY odd that it failed seeing as grace IS IN the fedora base repo
this should have installed it

Code:

su -
( type in the root password when asked ) 
yum install grace
