Prepare Gzip to be compiled:
./configure --prefix=/usr |
Change the default installation directory for Gzip so it will be installed in the /bin directory:
cp gzexe.in{,.backup} &&
sed 's%"BINDIR"%/bin%' gzexe.in.backup > gzexe.in |
Continue with compiling the package:
make |
Install the package:
make install |
Move the Gzip binaries to the /bin directory:
mv /usr/bin/gzip /bin &&
rm /usr/bin/{gunzip,zcat} &&
ln -s gzip /bin/gunzip &&
ln -s gzip /bin/zcat &&
ln -s gunzip /bin/uncompress |
