There's an app called Disk Arbitrator, install it, launch it then attach drive, app will mount it low level before OSX in read-only mode.

Maybe use perl instead, uses hash arrays use unique to remove redundant elements.

Thanks for all the help. I'll close this thread.

I don't understand the looping problem? Shouldn't sed scan the array and find the value the first loop?


for i in "${array[@]}"
do
a=`grep $i sub_c11* |cut -f2 -d","`
b=`grep $i sub_c13*...

Now when I add '-i' to do inline substitution, I still get my original error
sed -i "s/^$i.*/$i , $ratio/" sub_c18.csv
sed: 1: "sub_c18.csv": unterminated substitute pattern

Ugh...

Where did you put the file name?

I tried this
sed "s/^$i.*/$i , $ratio/" <$file2mod> test0

it the script goes into an infinite loop of re-writing the file, test0.

This is the code I used.

#!/usr/local/bin/bash
array=(61329025
61333750
61348174
61368157
61371144

61406775
61413072
61416814
61418304
61421223
61423127
61432337
61449549...

I tried both and they both started looping without stopping and not substituting.

After looking closely, there is a white space after the hex number.

This data file sub_c18.csv looks like this

Sure. Thanks for looking.

Thanks for reply.

I removed but still get this error.

ed: 1: "sub_c18.csv": unterminated substitute pattern

From what i've read the double '//' are needed to end the wildcard???

Thanks but that's not the issue, in my code it has parenthesis. I'll fix it.
