sed question from Ch 6.12


What is the purpose of `gcc --print-file specs` in this sed command:

sed -i 's@ /tools/lib/ld-linux.so.2@ /lib/ld-linux.so.2@g' \
`gcc --print-file specs`

Will sed execute

`gcc --print-file specs`

as a shell command? I didn't run the sed command from Chapter 6.12. Instead, I edited the specs file by hand. Should I then run

`gcc --print-file specs`

from the command line?
(Actually, I went ahead and did run

`gcc --print-file specs`

from the command line, and the response I got was only this:

/tools/lib/gcc/i686-pc-linux-gnu/3.4.1/specs

Since then, the rest of my LFS install has been going without trouble.)

if you edited by hand and changed the linker to /lib instead of /tools/lib you'll be alright. ` ` delimits a command. you will see this with library config executables to (like pkg-config and such) or even on the command line (cd /lib/modules/`uname -a`/kernel will change directory to the current running kernel's /lib/modules/<version>/kernel directory).
