fade [type] fade-in-length [stop-time [fade-out-length]]
Apply a fade effect to the beginning, end, or both of the audio.
An optional type can be specified to select the shape of the fade curve: q for quarter of a sine wave, h for
half a sine wave, t for linear (`triangular') slope, l for logarithmic, and p for inverted parabola. The
default is logarithmic.
A fade-in starts from the first sample and ramps the signal level from 0 to full volume over fade-in-length sec?
onds. Specify 0 seconds if no fade-in is wanted.
For fade-outs, the audio will be truncated at stop-time and the signal level will be ramped from full volume
down to 0 starting at fade-out-length seconds before the stop-time. If fade-out-length is not specified, it
defaults to the same value as fade-in-length. No fade-out is performed if stop-time is not specified. If the
file length can be determined from the input file header and length-changing effects are not in effect, then 0
may be specified for stop-time to indicate the usual case of a fade-out that ends at the end of the input audio
stream.
All times can be specified in either periods of time or sample counts. To specify time periods use the format
hh:mm:ss.frac format. To specify using sample counts, specify the number of samples and append the letter `s'
to the sample count (for example `8000s').

Several times, I find myself hitting my up arrow, and changing the search term. Unfortunately, I find myself wasting too much time typing:
$ grep kernel /var/log/messages
Redirecting STDIN allows me to put the search term at the end so I less cursor movement to change what I'm searching for:
$ < /var/log/messages grep kernel
If you're using the emacs keyboard binding, then after you press your up arrow, press CTRL+w to erase the word.
If this has already been submitted, I couldn't find it with the search utility.
