Copy dependent libraries into a chroot jail:

/bin/sh -c 'fifo="/tmp/ldd-$$"; mkfifo -m 600 ${fifo}; ldd /usr/sbin/sshd | cut -f2 | cut -d" " -f3 | tee ${fifo} | tail -n $(( $( cat ${fifo} | wc -l ) - 1 )); rm -f ${fifo}' | cpio --pass-through --make-directories /root/chroot/sshd/

Console Progress Bar for FreeBSD is in misc/clpbar

I've forgotten this three times already: DVDisaster
This looks interesting: Tarsnap

# Convert sha1(1)-compatible into cfv's sha1sum-format
sed -e 's#^SHA1 (\./\(.*\)) = \(.*\)$#\2 *\1#g' shas

# Convert cfv's sha1sum-format into sha1(1)-compatible
sed -e 's#^\([0-9A-Fa-f]\{40\}\) [* ]\(.*\)$#SHA1 (./\2) = \1#g' stuff.sha1
# Convert a list of strings into a sed script to filter said strings from another file
# Developed to filter a sha1 hashlist of all symlink-type files, which were computed separately
sed -e 's/[][\.*^$/]/\\&/g; s/^/\//; s/$/\/d/'

FreeBSD misdetects the amount of installed memory on a K7S5A Pro board with 1GB PC3200. Force it:

hw.physmem="1073741824"

Commonly used mkisofs options

mkisofs            # Command
 -v                # Verbose
 -gui              # Format output messages for use by GUI tools
 -iso-level 4      # ISO-9660:1999
 -D                # No deep directory relocation for ISO-9660:1999
 -J                # Generate Joliet records for Win32 systems
 -R                # Generate SUSP/RR records, using the Rock Ridge protocol, for Unix systems
 -r                # As -R, but normalizes certain values (uid/gid are 0, all entries are ugo+r-w, etc)
 -no-pad           # Do not pad ISO to 150 sectors (useful for DVDisaster or uzip images)
 -p CyberLeo       # Specify string for 'Preparer' volume header field
 -V FS-Label       # Specify string for 'Volid' (label) volume header field
 -o <file>.iso     # Name of file to hold resultant image
 <sourcedir> ...   # One or more directories whose contents will be shoved into the image root

Rubygems will no longer fall back to installing into ~/.gem if running as non-root. Provide --user-install on the gem command line to fix.
