vino

in the script that u had provided

all the files under the first for loop (outer for loop) would be listed

and since there is a break statement in the second for loop
for all the files from the outer for loop only the first file would be printed from the second loop.

To put in more specific terms
ls /data/logs
1.txt
2.txt

ls /data/errors
3.txt
4.txt

output would be:
1.txt 3.txt
2.txt 3.txt

the file 4.txt will not be listed

but the required output is of the form
xx-xx-xx-xx abc.log xx-xx-xx-xx abc.err
xx-xx-xx-xx abc1.log xx-xx-xx-xx abc1.err
xx-xx-xx-xx abc2.log xx-xx-xx-xx abc2.err

plz let me know if i had misinterpreted anywhere .

***********************
you can try this... (this is not an efficient way)

ls -l | /data/logs | grep -v total | awk '{print $1, $9}' > t
ls -l | /data/errors | grep -v total | awk '{print $1, $9}' > t1

paste -d"\t" t t1

would give the required output

DMXAddScreen(3) 					     Library Functions Manual						   DMXAddScreen(3)

NAME

       DMXAddScreen - attach a new back-end screen

SYNOPSIS

       #include <X11/extensions/dmxext.h>

       Bool DMXAddScreen(Display *dpy,
			 const char *displayName,
			 unsigned int mask,
			 DMXScreenAttributes *attr,
			 int *screen);

DESCRIPTION

       DMXAddScreen() attaches a back-end screen to the Xdmx(1) server, in place of the previously detached back-end server specified by screen.

       displayName  is	the name of the new back-end display, mask specifies the field in attr that are active, and screen returns the new Xdmx(1)
       screen number for the attached screen.

       The information stored in mask  and  attr is identical to that used  by	the  DMXChangeScreensAttributes(3)  and  DMXGetScreenAttributes(3)
       functions.

RETURN VALUE

       DMXAddScreen()  will  return  True if the screen was successfully attached, and False otherwise.  False will be returned if the -addremove-
       screens command line option was not specified on the Xdmx(1) command line, the input value of screen is out of range, screen  is  not  cur-
       rently  detached,  displayName  cannot  be opened, has unexpected visuals, or has characteristics that do not match the previously detached
       screen.

       DMXAddScreen() can generate BadLength, BadAlloc, and BadValue errors.

NOTES

       Attributes that are not specified will default to 0.  This may lead to unintended results.

       Unlike other functions in the DMX(3) API, this function uses screen for both input and output.
