My own hashfile format: [hashery.sh|CyberLeo/hashery.sh]

<code brush="bash">
# 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
</code>

<code brush="bash">
# 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:
<code brush="plain">
hw.physmem="1073741824"

Commonly used mkisofs options
<code brush="plain">
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.

This'll work for zfs-fuse on linux. FreeBSD needs camcontrol or atacontrol instead of hdparm.

<code brush="bash">
# Standby pool
sudo zpool status data | sed -e '/disk\/by/!d; s/^\W*//; s/  .*$//; s/^/\/dev\//' | sudo xargs /sbin/hdparm -y
# Check pool drive states
sudo zpool status data | sed -e '/disk\/by/!d; s/^\W*//; s/  .*$//; s/^/\/dev\//' | sudo xargs /sbin/hdparm -C
# Wake pool
sudo zpool status data | sed -e '/disk\/by/!d; s/^\W*//; s/  .*$//; s/^/\/dev\//' | sudo sh -c 'while read dev; do dd iflag=direct if="${dev}" of=/dev/null bs=512 count=1 & done; wait'
</code>

This prints out temperatures

<code brush="bash">
while sleep 5
do
  ( sensors -u | sed -e '/temp[0-9]*_input:/!d; s/^.*: //'
    nvidia-settings -tq [gpu:0]/GPUCoreTemp -q [gpu:1]/GPUCoreTemp 2>/dev/null
  ) | while read cpu0
  do
    read nb0
    read gpu0
    read gpu1
    printf "%s: CPU: %0.0fc  NB: %0.0fc  G0: %0.0fc  G1: %0.0fc\n" "$(date +%H:%M:%S)" "${cpu0}" "${nb0}" "${gpu0}" "${gpu1}"
  done
done
