Obviously For should be for (lowercase) like alister notes, but also, the content of the unquoted variable expansion $FILES is subject to field splitting (default: space, TAB or newline), which may lead to erroneous results and which will not occur with the second form...

Regarding the awk statement, it overwrites the content of /root/Desktop/output/$f.txt with every iteration of the loop.
Try
Code:
for ...
do
  ...
done > "/root/Desktop/output/$f.txt"

And like noted before in most cases variable expansions should be quoted, "$f" rather than $f
Hi friend
Thanks for your consideration.

when I run the code without copy the results, it is ok.

Code:
#! /bin/bash
FILES=/root/Desktop/decoder/input/*
for f in $FILES
do
awk '{$6=($1-64)/2 ;$7=((10^($6/10))/250)^(1/1.2) ; print}' OFS="\t" "$f";
done

But when I wanna save the results in separate txt files, it is not working.

Code:
#! /bin/bash
FILES=/root/Desktop/decoder/input/*
for f in $FILES
do
awk '{$6=($1-64)/2 ;$7=((10^($6/10))/250)^(1/1.2) ; print}' OFS="\t" "$f" > "/root/Desktop/decoder/input/out/"$f".txt "
done

I got this error:

Code:
[root@localhost decoder]# t1
./t1: line 6: /root/Desktop/decoder/input/out//root/Desktop/decoder/input/out.txt: No such file or directory
./t1: line 6: /root/Desktop/decoder/input/out//root/Desktop/decoder/input/SG1140103020247.CAP98RE.txt: No such file or directory
[root@localhost decoder]#

Furthermore, I tried to put output directory after done , but it is also not working.

I have a lot of files in Input and I want to have the results of all the files in separate folder.

Thanks in advance.
