Ok, I will admit right up front that this is stupid, and I shouldn't be hung up on this. I have a script that checks the unallocated areas of space, and checks to see if they are empty or not. If they aren't empty, I run xxd to allow for more analysis.
I have commented out the rest of the script for now. The following section checks if they are empty, and either disregards or creates the output file.
Code:
sum ./$iname/Unallocated*.raw | while read line
do
if [ `echo $line | awk '{print $1}'` = 00000 ]
then
echo $line | awk '{print $3 " is empty, disregarding."}'
else
echo $line | awk '{print $3 " is not empty. Creating XXD report"}'
ofname=`echo $line | awk '{print $3}'`
echo "xxd -a > ${ofname}.txt"
fi
done
No matter what I do, I can not get it to create the output files using the ofname variable. If I do echo $ofname, it shows correctly, but when I put it the xxd command, it's blank. Using echo to echo the xxd command back shows the filename as there.
As I said in the text, I was using echo to echo back the xxd command as it should be ran. This echos back the command just fine, file name and all. When I actually run xxd (not echo'ed), it doesn't have the file name. Usinb bash -xv, it shows the command as being 'xxd -a', with no file name attached at all.
I have tried putting the variable in (), {}, and any other crazy idea I had, and still nothing.
Any chance the output file name has embedded blanks or other special characters that are confusing bash? In other words, what are typical examples of what $ofname translates to?

I thought of that. But no.
The file names are generated by the script in the form of Unallocated-[start sector]-[end sector].raw, where [] denotes a variable. These files are created as expected.
Full script (keep in mind most of it is commented out) :
Code:
#!/bin/bash -xv
image="$1"
#Create a non-spaced, non-extensioned version of the filename for a folder name.
x="$image"
y=${x%%.*}
iname=`echo ${y##*/} | sed 's/ /_/g'`
#Determine if a folder with the same name as the image file exists, if not create.
#if [ -d $iname || -d Reports ]
# then
# read -a c -p"$iname or Reports folder(s) exists, continuing may overwrite previous data. Continue? (y/n)"
# if [ $c = n ]
# then
# exit 1
# fi
# else
# echo "folder does not exist, creating"
# mkdir $iname Reports
#fi
#
#Run MMLS to find empty portions of the disk, and find entries with 'Unallocated' in them.
#mmls "$image" | grep Unallocated | while read line
# do
# ssect=`echo $line | awk '{print $3+0}'`
# esect=`echo $line | awk '{print $4+0}'`
# bleng=`echo $line | awk '{print $5*512}'`
# fname=`echo $line | awk '{print "Unallocated-'${ssect}'-'${esect}'"}'`
# ewfexport -f raw -S 0 -o $ssect -B $bleng -t ./$iname/$fname "$image"
# done
#
#Determine if a file is empty or contains data.
#echo "Results of sum command against all generated raw files" > $iname-sumresults.txt
#sum ./$iname/Unallocated*.raw >> $iname-sumresults.txt
sum ./$iname/Unallocated*.raw | while read line
do
if [ `echo $line | awk '{print $1}'` = 00000 ]
then
echo $line | awk '{print $3 " is empty, disregarding."}'
else
echo $line | awk '{print $3 " is not empty. Creating XXD report"}'
ofname=`echo $line | awk '{print $3}'`
`xxd -a > "$ofname".txt`
fi
done
As part of a bash the below line strips off a numerical prefix from directory 1 to search for in directory 2.
for file in /home/cmccabe/Desktop/comparison/missing/*.txt
do
file1=${file##*/} # Strip off directory
getprefix=${file1%%_*.txt}
