Question how to understand this shell code?


I am new to LFS.
when I got to the STEP 5.7 Adjusting the Toolchain I got some problem.
perhaps I should understand the below code:

mv -v /tools/bin/{ld,ld-old}
mv -v /tools/$(gcc -dumpmachine)/bin/{ld,ld-old}
mv -v /tools/bin/{ld-new,ld}
ln -sv /tools/bin/ld /tools/$(gcc -dumpmachine)/bin/ld
gcc -dumpspecs | sed 's@^/lib/ld-linux.so.2@/tools&@g' > `dirname $(gcc -print-libgcc-file-name)`/specs
GCC_INCLUDEDIR=`dirname $(gcc -print-libgcc-file-name)`/include &&
find ${GCC_INCLUDEDIR}/* -maxdepth 0 -xtype d -exec rm -rvf '{}' \; &&
rm -vf `grep -l "DO NOT EDIT THIS FILE" ${GCC_INCLUDEDIR}/*` &&
unset GCC_INCLUDEDIR


Thanks your help!

That is a shell script, Shellcode is pretty different.
Anyhow what sort of a problem are you facing?
All of the commands are pretty basic...
