If it is no problem to seek every list for the names instead of skipping some, you could write the names into a file "namelist" for example and then do something like:
Else you can write the names into a list like above also save the lists into an array, in ksh for example
and then work the array by incrementing it's element's index by one in a for loop when working the array against the name list, using "grep -lf namelist ${array[n]}".

I need help getting over this bump on how nested for loops work in shell. Say i was comparing files in a directory in any other language my for loop would look like so
for(int i=0;to then end; i++)
for(int y = i+1; to the end; y++)
I can't seem to understand how i can translate that... (5 Replies)
You can use one while inside another?
I made the following script (without really knowing if I can use two while) to get 3 numbers different from each other at random:
num1=$(( $RANDOM % 10 ))
num2=$num1
while
do
num2=$(( $RANDOM % 10 ))
done
num3=$num1

KSH isn't my strong suit but it's what my company has to offer. I've got a script with two nested loops, a FOR and UNTIL, and that works fine. When I add a CASE into the mix I end up getting "Unexpected 'done' at line xx" errors. Any suggestions on this?

Hello, I pulled out some old code from an unfinished project the other day and wanted to stream line it better. I know anything beyond a double loop is usually bad practice, and I came up with some logic for later that would no longer require the first loop in the following code that works:

scandir
SCANDIR(3) Library Functions Manual SCANDIR(3)NAME
scandir, alphasort - scan a directory
SYNOPSIS
#include <sys/types.h>
#include <sys/dir.h>
scandir(dirname, namelist, select, compar)
char *dirname;
struct direct *(*namelist[]);
int (*select)();
int (*compar)();
alphasort(d1, d2)
struct direct **d1, **d2;
DESCRIPTION
Scandir reads the directory dirname and builds an array of pointers to directory entries using malloc(3). It returns the number of entries
in the array and a pointer to the array through namelist.
The select parameter is a pointer to a user supplied subroutine which is called by scandir to select which entries are to be included in
the array. The select routine is passed a pointer to a directory entry and should return a non-zero value if the directory entry is to be
included in the array. If select is null, then all the directory entries will be included.
The compar parameter is a pointer to a user supplied subroutine which is passed to qsort(3) to sort the completed array. If this pointer is
null, the array is not sorted. Alphasort is a routine which can be used for the compar parameter to sort the array alphabetically.
The memory allocated for the array can be deallocated with free (see malloc(3)) by freeing each pointer in the array and the array itself.
SEE ALSO directory(3), malloc(3), qsort(3), dir(5)DIAGNOSTICS
Returns -1 if the directory cannot be opened for reading or if malloc(3) cannot allocate enough memory to hold all the data structures.
