Very Computer

I have a data file "spectrum.tmp", which contains 15 lines and
each line is a name of file.
How can I read them line by  line?

The followin is what I'm doing now.  Is there any more elegant way?

count=1
awk 'NR=='"$count"'{print}' spectrum.tmp > numnrg.tmp
count=`expr $count + 1`
read tmpfil < specfil
cp $tmpfil weight
.
.
.
awk 'NR=='"$count"'{print}' spectrum.tmp > parameters.tmp
count=`expr $count + 1`
read tmpfil < parameters.tmp
echo "$tmpfil"
.
.
.

Thank you very much in advance.

        awk '  
        NR==1   { print "cp", $1, "weight" }
        ...
        NR==7   { print "echo", $1 }
        ...
        NR==15  { print "whatever", $1 }
        ' < spectrum.tmp | /bin/sh

2) In ksh, you could read the file names into an array, and then
operate on the array:

        set -A tmpfile $(<spectrum.tmp)
        cp ${tmpfile[1]} weight
        ...
        echo ${tmpfile[7]}
        ...

while read FILENAME
do
        while read LINE
        do
                echo What ever you want to do with this LINE
        done < $FILENAME
done < file_with_filenames

#! /bin/sh
# readline      Read one line at a time from a file
#
while read Line
do

    #< do something to $Line >
    #< if you want to exit when you find something -- use 'break' >
    echo $Line

done < $1

Usage: readline file_name

>Usage: readline file_name

zsh% sh
$ onx=1
$ while read line

Quote:> do
>   echo blah $line
>   onx=2
> done < $HOME/.forward

So, the variable's new setting was lost.

I'm not sure I understand your question entirely, but here's how to
read a file containing a list of files to be read.  It also reads
each file to be read as it gets the corresponding filename.

#!/bin/sh

while read FILENAME
do
   while read LINE
   do
      echo "LINE: $LINE"
   done < $FILENAME
done < $1

It gets the master file (containing a list of files to read) from
the command line.

Hope that was what you were asking...

cat spectrum.tmp |while read FILENAME
do
        cat $FILENAME |while read LINE
        do
                echo $LINE
        done
done

cat `cat spectrum.tmp` |
while
        read LINE
do
        # something
done

# another way of going about the same thing (and perhaps better!).
# uses only two "cats" & only requires a one stage loop. this example
# shows use of command substitution. the other example (above mine) uses
# "cat" once for each word in the file spectrum.tmp + 1 initial "cat" to
# get the file names. trouble with my example is that the loop won't know
# which file it is reading lines from (might be needed in user's program).

while read -r LINE
do
    echo $LINE
done < spectrum.tmp

  -- or, to break each line up into tokens --

while read -r T1 T2 T3 T4 REST
    echo "Token #2 is" $T2
done < spectrum.tmp
