Hi Don,

I wish!

Okay, here's what I've go so far:

Code:

#!/bin/bash

#
# 1. Read in input file and separate out filename
# 2. Search for it
# 3. Copy it in a directory
# 4. Create file with old and new file paths

outdir=/Users/pc/test/newdata
outfile=copyDetails.txt
ofile=${outdir}/${outfile}
header="From    To"
echo "${header}" >> $ofile

while read Barcode Sampleid Other
do
        [ "$Barcode" == "barcode" ] && continue
        pattern="*${Barcode}*"
        names=`find /Users/pc/test -name "*${Barcode}*"`
        myname=`echo $names | cut -d' ' -f1`
        cp ${myname} ${outdir}
        from=$myname
        to="${outdir}/${Barcode}"
        oline=`echo ${from}"\t"${to}`
        echo ${oline} >> $ofile


done < ../data/worksheet.txt


echo "Finished"
exit 0

Not elegant, but works for the original purpose. The input file has 3 columns and the filename is in the column 'Barcode'. I am also trying to create a file that will keep a record of the origin and destination of the file. My questions:

1. The code lines:

Code:

        oline=`echo ${from}"\t"${to}`
        echo ${oline} >> $ofile

don't give a tab separated output. The '\t' is written into the file as it is. What am I doing wrong?

2. Any comments to improve the code -- I'm just beginning here...

thanks!!

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
