Linux Wrong output when writing to file
Hello,

I am having problem while redirecting output to a file where as on console output is proper.

Code:
for dir in */; do printf "%s, " "$dir"; ls -m "$dir"; echo; done > output.txt

Output of above command is coming in single line but when i am redirecting output to a file, single line i breaking into multiple line.

Sample Output of Console(output is coming in single line) :

Code:
activestop.nicorette/, activestop_nicorette, prod-activestop_nicorette, prod-activestop_nicorette, prod-activestop_nicorette

Sample output in file (same format is coming in file):

Code:
activestop.nicorette/, activestop_nicorette, 
activestop_nicorette,activestop_nicorette,
activestop_nicorette

please suggest.

You need to make it a single line list first.
Code:
list="";for l in *;do list+=", $l";done;echo "$list" > output.txt

Which is just the same as:
Code:
list=""
for l in *
do  list+=", $l"
done
echo "$list" > output.txt

Its is just printing main directories not the sub-directories/files..

Define your desired output and give an example of input.
Also in your example code, you do quite a double work, since ls -m already produces the output you listed.

You might just change to:
Code:
ls -m "$dir"/*

Thought , you need to check if its really a directory first.

Not sure what you want, find might be helpful

find / will give you EVERY directory and file

find . will give you EVERY directory and file in your current directory

The description of the ls -m option in the standards is:
Quote:
Stream output format; list pathnames across the page, separated by a <comma> character followed by a <space> character. Use a <newline> character as the list terminator and after the separator sequence when there is not room on a line for the next list entry. This option disables long format output.
The default line width for a regular file is probably something like 80. I have no idea what line length you have set up for your console.

You could try something like:
Code:
COLUMNS=1000000 ls -md */ */*/

to list directories in the current directory and the directories in those directories on one line (assuming that no more than one million display columns are needed to print that line). Note, however, that if the value you set for COLUMNS is larger than the value you get from:
Code:
getconf LINE_MAX

(which on many systems is 2048), then the standard text processing utilities might not work on your resulting file.

And, note that your description of what you are trying to print is very vague. Without some idea of what your file structure looks like and what you hope to print from that file structure, we are all just guessing.
