Quick way to move an entire tree of files from one disk to another
(cd /source/directory; tar cf - . ) | (cd /dest/directory; tar xvf -)

I don't know if many people have this problem, but there is a "feature" of GNU
make version 3.70 that I don't like. It is that VPATH acts funny if you give it
an absolute pathname. There is an extremely solid patch that fixes this, which
you can get from Paul D. Smith <psmith@wellfleet.com>
. He also posts the
documentation and patch after every revision of GNU make on the
newsgroup `gnu.utils.bug'.
Generally, I apply this patch and recompile gmake on every
system I have access to.

Q: How do I stop e2fsck from checking my disk every time I boot up.
A: When you rebuild the kernel, the filesystem is marked as 'dirty' and so your disk will be checked with each boot. The fix is to run:
rdev -R /zImage 1
This fixes the kernel so that it is no longer convinced that the filesystem is dirty.
Note: If using lilo, then add read-only
to your linux setup in your lilo config file (Usually /etc/lilo/config)

If you often get device busy errors on shutdown that leave the filesystem in need of an fsck upon reboot, here is a simple fix:
To /etc/brc
or /sbin/brc
, add the line
mount -o remount,ro /mount.dir
for all your mounted filesystems except /, before the call to umount -a. This
means if, for some reason, shutdown fails to kill all processes and umount the
disks they will still be clean on reboot. Saves a lot of time at reboot for
me

I call this script 'forall'. Use it like this:
forall /usr/include grep -i ioctl
forall /usr/man grep ioctl
Here's forall:
#!/bin/sh
if [ 1 = `expr 2 \> $#` ]
then
echo Usage: $0 dir cmd [optargs]
exit 1
fi
dir=$1
shift
find $dir -type f -print | xargs "$@"
