Detail on For loop for multiple file input and bash variable usage

Dear mentors, I just need little explanation regarding for loop to give input to awk script

Code:
for file in `ls *.txt |sort -t"_" -k2n,2`; do

awk script  $file

done

which sorts file in order, and will input one after another file in order to awk script

suppose if I have to input 2 or more than two file in order to awk what I need to do

case is something like this

Code:
for loop

awk script file_1 file_2 file_3

done

in next increment it should
Code:
input file_4 file_5 and file_6

and I do program normally by FORTRAN or C, don't know much about shell

every time I have to edit in and out file in Fortran code and then I have to compile and run .for code

is there any solution like EOF for fortran to use bash variable in fortran code for in and out file replacement and execute the same.



Kindly anyone explain on this topic.

continue(3tcl)						       Tcl Built-In Commands						    continue(3tcl)

__________________________________________________________________________________________________________________________________________________

NAME
continue - Skip to the next iteration of a loop SYNOPSIS
continue _________________________________________________________________ DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code, which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as the catch command and the outermost scripts of procedure bodies. EXAMPLE
Print a line for each of the integers from 0 to 10 except 5: for {set x 0} {$x<10} {incr x} { if {$x == 5} { continue } puts "x is $x" } SEE ALSO
break(3tcl), for(3tcl), foreach(3tcl), return(3tcl), while(3tcl) KEYWORDS
continue, iteration, loop Tcl continue(3tcl)
