listing sequential files as one group...

kentm · January 24, 2007, 2:09pm

Hi,

I posted this over at Macnn and was redirected here... I'm not a unix programmer at all, but I have some backup if needed. Thanks in advance for any input.

Is there a command for the osX terminal that will list sequentially numbered groups of file as one line instead of individually, while listing other files and directories correctly?

Meaning that a group of files:

image.001.tif
image.002.tif
image.003.tif
image.004.tif
image.005.tif

would be listed as

image.001-005.tif

and a dir with other files and dirs:

image.001.tif
image.002.tif
image.003.tif
image.004.tif
image.005.tif
dir01/
dir02/
imageB.tif

in it would be:

image.001-005.tif
dir01/
dir02/
imageB.tif

?

Wold love to have this...

Thanks,
KM

Surely this can be done better, but it was a quick job

----------------------------------------------------------------
script
----------------------------------------------------------------

#!/usr/bin/ksh

for DIR in `find tmp -type d`
do
EXPECT=""
FIRST=""
LAST=""

for FILE in `find ${DIR}/* -prune -type f 2> /dev/null`
do
if [ "${FILE}" != "${EXPECT}" ]
then
if [ "${LAST}" != "" ]
then
if [ "${FIRST}" == "${LAST}" ]
then
echo "${FIRST}"
else
typeset -i LEN
((LEN=`echo ${LAST} | sed -e "s/.*[^0-9]$[0-9][0-9]*$[^0-9]$/\1/" | wc -c`-1))
typeset -Z${LEN} NUM NEXTNUM
NUM=`echo ${LAST} | sed -e "s/.*[^0-9]$[0-9][0-9]*$[^0-9]$/\1/"`
echo "${FIRST}" | sed -e "s/$[^0-9][^0-9]*$$/-${NUM}\1/"
fi
fi
FIRST=${FILE}
fi

LAST=$\{FILE\}

echo $\{LAST\} | grep [0-9] &gt; /dev/null
if [ $\{?\} -eq 0 ]
then
  typeset -i LEN
  \(\(LEN=\`echo $\{LAST\} | sed -e "s/.\*[^0-9]\\\([0-9][0-9]\*\\\)[^0-9]*$/\\1/" | wc -c\`-1\)\)
  typeset -Z$\{LEN\} NUM NEXTNUM
  NUM=\`echo $\{LAST\} | sed -e "s/.\*[^0-9]\\\([0-9][0-9]\*\\\)[^0-9]*$/\\1/"\`
  \(\(NEXTNUM=$\{NUM\}\+1\)\)
  EXPECT=\`echo $\{LAST\} | sed -e "s/$\{NUM\}/$\{NEXTNUM\}/"\`
fi

done

if [ "${LAST}" != "" ]
then
if [ "${FIRST}" == "${LAST}" ]
then
echo "${FIRST}"
else
typeset -i LEN
((LEN=`echo ${LAST} | sed -e "s/.*[^0-9]$[0-9][0-9]*$[^0-9]$/\1/" | wc -c`-1))
typeset -Z${LEN} NUM NEXTNUM
NUM=`echo ${LAST} | sed -e "s/.*[^0-9]$[0-9][0-9]*$[^0-9]$/\1/"`
