Hi,
This might be a silly question, but should strip work across symbolic links?
For example, I executed the following sequence of commands in bash (comments
added later) and found that the files striped via a symbolic link are
truncated and unexecutable. Is this "normal" behaviour or a bug?
I am executing the following command and finding that my cygwin installation
is no longer usable afterwards.
bash-$ find /usr/local/cygwin-b20.1 \( -name "*.dll" -or -name "*.exe" \)
-print -exec strip --strip-all {} \;
Regards,
David
