I'm having a problem with the following command:

SPECFILE='gcc --print-file specs' &&
sed 's@ /lib/ld-linux.so.2@ /tools/lib/ld-linux.so.2@g' \
$SPECFILE > tempspecfile &&
mv -f tempspecfile $SPECFILE &&
unset SPECFILE



When i run these commands instead of doing anything it displays the data for sed as if the command syntax is wrong. I have copy and pasted as well as typed this by hand. I have checked /lib for the dynamic linker and it is in fact ld-linux.so.2. My questions are:

A. What if anything am i doing wrong?

B. What if anyone could tell me are the manual commands needed to do this by hand instead of using the script?

C. Could anybody offer any other information that i haven't thought of?

Any and all help would be appreciated.

Thanx

It's hard to tell what's wrong, but my first guess would be that:

should really be

SPECFILE=`gcc --print-file specs` &&

(i.e. single quotes replaced by backquotes).

Incidentally, all that script does (apparently) is replace every instance of "/lib/ld-linux.so.2" with "/tools/lib/ld-linux.so.2" in the file named by the output of the command "gcc --print-file specs". So you could fire up a text editor to do that manually if you wish.

Interesting possibility. Should i replace all quotes with the back quotes?

No! The single quotes in the sed command are correct.

You need backquotes only when you want to grab the output of a command. In this case, gcc --print-file specs presumably gives you the name of a file that is interesting and relevant, so the backquotes are used to get that filename into the variable SPECFILE.

Okay cool, i will give that a try this evenging, and let you know.

Everything worked perfect. Thanx
