2021-06-03tweewide: Fix most Shebang linesFinn Behrens
commit c25ce589dca10d64dde139ae093abc258a32869c upstream. Change every shebang which does not need an argument to use /usr/bin/env. This is needed as not every distro has everything under /usr/bin, sometimes not even bash.

2015-08-28scripts: add stackdelta scriptRasmus Villemoes
This adds a simple perl script for reading two files as produced by the stackusage script and computing the changes in stack usage. For example: $ scripts/stackusage -o /tmp/old.su CC=gcc-4.7 -j8 fs/ext4/ $ scripts/stackusage -o /tmp/new.su CC=gcc-5.0 -j8 fs/ext4/ $ scripts/stackdelta /tmp/{old,new}.su | sort -k5,5g shows that gcc 5.0 generally produces less stack-hungry code than gcc 4.7. Obviously, the script can also be used for measuring the effect of commits, .config tweaks or whatnot.
