That is using a feature of the date utility on your system; not a feature of bash. On systems that don't have the --d option to date, the following ksh
script should work:
Code:
cat formdate

#!/bin/ksh
# input argument format MM-<Abbreviated_Month>-YYYY
# output format YYYYMMDD
typeset -A month
month=( [JAN]=01  [FEB]=02  [MAR]=03  [APR]=04  [MAY]=05  [JUN]=06
	 [JUL]=07  [AUG]=08  [SEP]=09  [OCT]=10  [NOV]=11  [DEC]=12 )
while [ $# -gt 0 ]
do
	abmon=${1%-*}
	abmon=${abmon#*-}
	printf "%s%s%s\n" "${1##*-}" "${month[$abmon]}" "${1%%-*}"
	shift
done

Code:
formdate 26-JUL-2012 01-JAN-2000 31-DEC-2013
20120726

CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
