What can we do if we type chmod ugo-x /bin/chmod ??????

Hi everyone!

If we type chmod ugo-x /bin/chmod we can't make chmod executable again (or for that matter any other mode change...).

Is there some way (other than reinstalling chmod or writing a c program to change modes) to do anything?

Thanks

You could use a live disc.

Mount your root drive and chmod +x /path/to/mountroot/bin/chmod

Or you can take any existing executable and overwite it:

cp /bin/ls ~/ls
dd if=/bin/chmod of=~/ls
~/ls a+x /bin/chmod

aaa's solution is cool!

Thanks to you both for replying!
