Doesn't work that way. It wouldn't have a real file name, in any case; it'd try to open a file and complain that it didn't exist.

A named pipe may be useful. It'll effectively be a file my_tool...

The code that you posted was actually comparing 2nd field in file2 with 2nd field in file1:
awk 'NR==FNR{a[$2]=$0;next}a[$2]{$0=a[$2]}1' file2 file1
But your requirement was to compare it other...

Try this:
awk 'NR==FNR{A[$2];next}$2 in A' file1 file2

?_?
~/unix.com$ cat file1

~/unix.com$ cat file2

You could try this:

for num in {1..400}
do
echo "Processing directory #${num}"
cd /home/my_dir/hour_${num}
dos2unix -q -n hour_${num}.txt tmp.txt
paste tmp.txt...

EDIT: What felipe said :).

So this should work:
find /home/tester/datasets/ -name "hour_*.txt" -type f | \
while read fname
do
fileBaseName=`basename "${fname}"`
fileDirName=`dirname...

The problem is because awk's FILENAME points to the filename and path, not only the filename!

Try to change FILENAME to:

# E.g. awk '{ns=split(FILENAME, arr, "/"); print arr[ns]}' <infile>
#...

Please, execute the command below:

find /home/dataset -maxdepth 1 -name "hour_*.txt" -type f


I think it is an environment issue, because some "find" command distributions does not accept the:...

One way:
awk 'FNR>2{print > "new_" FILENAME}' *

Something like this?
awk '{print > "new_" FILENAME}' RS=" " file*.txt

No, this is not a Cygwin issue.

Consider the following (rigth now, I'm on Cygwin too):

This is the content of the two input files: file1 and file2:

% head file[12]
==> file1 <==
1 ...
