Then best look at your course material, ask your instructor to explain lessons 1 through 10 again or read some basic tutorials as you've shown no knowledge of shell scripting at all in this or your previous thread:

Code:

function help() { echo "Bash scripting guides:

Sorry, but unSpawn gave you a good answer, with good direction.

If you have to write a script, and all you've done is ONE LINE....that's not much effort into it, especially when first two links that he provided tell you explicitly how to use variables, loops, etc. If you don't want people to 'junge' you, post the rest of the script you've written, and where you're stuck.

It doesn't show. And backing up what script requirements you've posted only with a 'find' line doesn't show us anything that we can correct to help you with.

It's not a question of judging you or not. The reason why I said that is that asking for handouts doesn't make you learn anything. Here's what you want:

Code:

newfile <( find micro -type f -iname sound_\* -printf "( sed -n \$(basename %p|cut -d '_' -f 2),1p \"%p\" )\n"|/bin/bash )

...but in a way you won't be able to explain to your teacher.

We help you, you post your script.
That's called reciprocity.
So please do.

Sorry to shoot off at something of a tangent, but you are not helping yourself by making your posts easy to read. Here is your first post in this thread re-formatted to include things like capital letters, spaces between sentences and dropped the idiotic excess exclamation marks where it adds nothing at all to the meaning (I have no objection to the use of a single exclamation mark where something exceptional is being pointed out, or to emphasise a point that it easily missed, but to use them just because you are bored with full stops gets wearing very rapidly), so that readability is increased.

Hello.

I have to find all the files which have the name sound_x, from a directory which is called micro. The x is a variable and the files names are sound_5,sound_38,sound_101 (note, you seem to be saying that it is always an integer; that is not the same as saying that it a variable, so be as informative as possible)..etc...

I want to create a file (name newfile) which contains the line 5 from the file sound_5,the line 38 from the file sound_38,the line 101 from the file sound_101. This file, newfile, should be sorted, for example line 5 should be above line 38 in the new file.

So far all I have is this:

Code:

find . -name "sound_*" fprint "temporary_files"

I hope that you agree that this is more readable. While, in any case what you choose do up to you, you need to take into account that if your post is difficult to read, many people will just jump to another post and those who do come to your post may not be as helpful to you if you hadn't made them work to even understand what you are saying. Please do try to act in your own best interests.

done:

Quote:

find ./micro -name "sound_*" -fprint "sound_x_files.txt"
cat sound_x_files.txt | cut -d "_" -f 3 > output.txt
cat output.txt | cut -d "." -f 1 > output.txt

sort -n output.txt > sort_output.txt
mkdir new_folder

while read w
sound_x
do
cp ${w} new_folder
done < sound_x_files.txt

while read y
do
sed -n ${y}p ./new_folder/sound_${y}.txt >> new_file.txt
done < sort_output.txt

while read k
do
echo " ${k} "
done < new_file.txt

Hmm.

Code:

cat sound_x_files.txt | cut -d "_" -f 3 > output.txt
cat output.txt | cut -d "." -f 1 > output.txt

This would only print out the literal string "files" and not the "x" position where the number is:

Code:

find ./micro -type f -name "sound_*.txt" | while read ITEM; do
 NUMBER=$(echo ${ITEM}|cut -d "_" -f 2)
 #  ...or make it an array, then select array item 2:
 # NUMBER=(${ITEM//_/ }); NUMBER=${NUMBER[1]}
