The thing is...
The thing is, the input files vary. It could be in logs, records, database, information converted into plain text. The script will need to be able to read everything on it. One file for example had:

Code:
John Smith  555-5555  to 555-5555 Hello Jane Doe

another file was an email message so it was all text

The output just needs to have everything taken from the input printed in the output. The problem here is that it needs to be collectively done. For example I input one file and output it to the output file. Input another file and output it to the same(adding into) output file. That's where I'm stuck. I read that it will overwrite it the existing file, but I was wondering if it can be updated instead.

Quote:
define gibberish
gibberish meaning non-printable that might be mixed into the regular expressions


Update:

so for the while loop portion where it reads I can use this code correct?

Code:
while read line 

do echo "${line}"

 done < <(cat file.lst)

/tmp/file1.txt
/tmp/file with space.txt

which inputs a file list of files to extract content out of and output it into a txt file in temp?

---------- Post updated at 07:38 PM ---------- Previous update was at 04:52 PM ----------

Will this also work?

Code:
cd <input_file_directory>
for file in `dir -d *` ; do
<exeFile with full path> "$file" <output_file_path/"$file".out>
done
