Ensure path permissions from '.' prior to root

pwd|grep -o '/'|perl -ne '$x.="./.";print`readlink -f $x`'|xargs -tn1 chmod 755
`pwd` returns the current path `grep -o` prints each slash on new line perl generates the paths sequence: './.', './../.', ... `readlink` canonicalizes paths (it makes the things more transparent) `xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR.
Sample Output
chmod 755 /tmp/1/2/3 
chmod 755 /tmp/1/2 
chmod 755 /tmp/1 
chmod 755 /tmp
