Shell Programming and Scripting

Are you sure that it's interpreted by bash? Or is it part of a script that has a #!sh shebang?

A shell that does not understand this would throw an error.

In case you have two or more extensions, e.g. file1.txt.txt, then you get

Code:

echo ${file%.*}
file1.txt

Perhaps you need

Code:

echo ${file%%.*}
file1

Sorry all my shell is

Code:

#!sh

Thanks made in Germany but your suggestion doesn't work!

Please run the script with the -x option set and post the output.

Really sorry guys the solution of MadeinGermany works fine...I had a my mistake!

Sorry for annoying you!

Thanks

No trouble, though I'm left curious what the issue was

my fault..

Usage is

Code:

command [options] <input> <ouput.prefix>

my command for this site was was

Code:

for file in /path/to/*.txt
do command -input $file -output "${file%.*}"_sorted.txt
done

My real command was

Code:

for file in /path/to/*.txt
do command $file -o "${file%.*}"_sorted.txt
done

That was because I though was more clear specify INPUT and OUTPUT for you.
BUT
My mistake was to think that

Code:

-o

was

Code:

output

when instead is

Code:

final output to stdout

well that was do not know how it matter..
hope that my awful explanation is clear.. better I go home now!

still sorry for my mistake next time i'll read carefully the options!

best
