I agree with you. However, I think that there must be a way to reduce
user problems, and as usual in life, a price has to be paid for that.
So, I am dropping the word "like", and also, I do not "dislike" this
script.
1. I have run the previous posted script, then the new one, and logged
both. A "diff" showed no difference in the outputs.
2. A "diff" was between the scripts, not their output, gave (just
pasting the lines that could have some interest, although it is not
really an important point):
<paste>
$ diff -Naur ../../lfs/version-check-lfs-support{,-2}.sh | less
...
SH=`readlink -f /bin/sh`
echo "/bin/sh -> $SH"
-[ "$SH" == "/bin/bash" ] || die "/bin/sh is not a symlink to bash"
+[ "$SH" == "/bin/bash" ] || die "/bin/sh is not a symlink to bash"
...
</paste>
There is an extra space in the new one, just after "==".
