How to Removing a dot from a file name?
I need a script that will allow me to rename all of my files in subdir /FilesIn
as follows:


From kumc_835_111200.RMT.dat to kumc_835_111200RMT.dat
kumc_835_111200.KMR.dat to kumc_835_111200KMR.dat

.................etc


How do I do that whithout doing a sed 's/.RMT/RMT\g' since the file name is not always .RMT.DAT !!

Thanks

Code:
ls | while read FILE
do
        IFS="."
        set -- $FILE
        if [ $# -eq 3 ]
        then
                echo mv "$FILE" "${1}${2}.${3}"
        fi
done

  mv "$file" "${file%.*}.$suffix"

do you want to add .DAT to all file names and remove all other dots?

your first example was showing that all your files are ending with .dat and you wish you remove all dots other than the one before dat.

awk : (the ls or find cmd to get the file name is omitted)

Code:
kent$  echo "a.b.c.d.f.dat"|awk -F'.' 'BEGIN{OFS=""}{s=$NF;o=$0;$NF="";print "mv "o" " $0"."s}'                                          
mv a.b.c.d.f.dat abcdf.dat

add |sh at the end of the command line will do the rename.


kent$  echo "a.b.c.d.f.dat"|awk -F'.' 'BEGIN{OFS=""}{s=$NF;o=$0;$NF="";print "mv "o" " $0"."s}' |sh
