UNIX for Dummies Questions & Answers

Hi guru's

I am new to UNIX. requirement is merging all text files from one folder in the order which they have received.

EX: under /Test folder files received in certain intervals.

Code:

abc.txt     @ 1:00 AM
123.txt     @ 2:00 AM
xyz.txt     @ 4:00 AM
.
.
.
456.txt     @ 10:00 PM

so need to develop a script to merge all the files into FINAL.txt and move to another folder(/Final)( hoping the order of merging files should be abc.txt,123.txt...456.txt) . Reason for this is last file will have some indicator which need to appended at the end of the file only.

Appreciate your help.

Thanks
Arun

Hi Arun,
You can use the following script ......

Code:

rm -r final 1>/dev/null 2>/dev/null
for i in `ls -l |grep -v total|sort +5|awk '{print $9}'`
do
cat $i >>final
done

Try:

Code:

ls -trl |awk '/^-/{ print $NF }' | xargs cat - >/dir/final.txt

Code:

cat abc.txt 123.txt xyz.txt ... 456.txt > outputfile

That's the best thing I can think of.

EDIT: Disregard that. I realize that this is a pretty useless solution that was probably already obvious.

I think this works

Code:

rm final.out
ls -lart | awk '{print $9}' |xargs cat >final.out
