If mv would let you invert the order of its arguments, an ls | awk |
xargs | mv pipe would take care of this, but it doesn't so (I did this
from tcsh):
If the filenames actually have 1999 in them:
( echo '#\!/bin/sh' ; ls -tl | awk '/1999/ {print "mv " $9 "
/home/darryl/test"}' ) > mvfile
sh mvfile
If the file's mtime is 199 and you don't care about what's in the
filename:
( echo '#\!/bin/sh' ; ls -Ttl | awk '($9 == 1999) {print "mv " $10 "
new"}' ) > mvfile
sh mvfile
Note that these will fail for files whose filenames contain spaces.
