sed -e 's|in \(.*\$PATH\)|in `echo \1`|' configure...: This fixes a little problem in man's configure. The configure-script looks for files like cat, gunzip, bzip2, etc. in a for-loop that walks through a specified path. The splitting of the path is not done correctly and needs that fix. -default: This configures the man package with default settings. sed s/AWK=/"AWK=\/usr\/bin\/mawk"/ /usr/sbin/makewhatis > makewhatis-new: This modifies /usr/sbin/makewhatis's AWK variable and fills in the location of the mawk program. chmod 755 /usr/sbin/makewhatis: This makes the makewhatis script executable again.
