I have file 1 which contains:

AAAAAA

BBBBBB

I have file 2 which contains:

11111 22222 33333

and file 3 which contains:

22222 11111 33333

I want to insert each line in file 1 into file 2 and 3 replacing '11111' and creating a new file each time.
So the end result is 4 files:

File 1:

AAAAAA2222233333

File 2:

BBBBBB2222233333

File 3:

22222AAAAAA33333

File 4:

22222BBBBBB33333

I have attempted to use a nested for loop and sed to replace the values, at the moment I have this; however, it does not work:
(directory/* contains file 2 and file 3)

FILES=/directory/*

cat file1 | while read line ;do

    for f in $FILES; do



            cat $f | sed 's/11111/$i/g' > newfiles/$f$i.txt



    done



done

Each time I run the script there may be a different number of files to edit, so I would like to iterate over the directory to make sure all files are covered. There will also be different numbers of strings in file 1.

You need to iterate through the substitution file and then loop the target files. I think you are almost there. I have something like the following (I subbed some file names so that the globbing would work):

!/bin/bash



i=1

FILES=./other_file*

while read r; do

    for f in $FILES; do

        sed "s/11111/$r/g" > newfiles/file$i.txt < $f

        i=$(( i + 1 ))

    done

done <file1

Here we first indicate that we are using bash as the shell. Then set a counter i to 1. Next glob the files into a variable. The loop through file1 and assign each line to variable r. Then for each of the files sub the 11111 string with whatever we saw in the line. Output it to a new file using the counter in the name and then increment the counter. Repeat until the loops are done.

How about Awk? save the mappings from file1 into an associative array, and then loop over the array for each line of the other files:

awk -v OFS= '

  NR==FNR {t[NR]=$0; next} 

  {s = $0} 

  {

    for(i in t) {

      $0 = s; 

      sub(/11111/,t[i]); 

      $1=$1; 

      print > "newfile" ++n

    }

  }' file1 file2 file3

(the OFS= and $1=$1 are just to force the record to be re-evaluated with en empty field separator, so as to remove the spaces between fields). Results:

$ head newfile*

==> newfile1 <==

AAAAAA2222233333



==> newfile2 <==

BBBBBB2222233333



==> newfile3 <==

22222AAAAAA33333



==> newfile4 <==
