The second option will change all files in a directory, you want one file, just:
Code:
sed -e '1,$s/old string/new string/g' myfirstfileinloop.txt > myfirstfileinloop.txt.new

Also, in the second option you can rename the tmp file to the original one:
Code:
ls -1 | while read fname
do
      myFileTmp=${fname}.tmp
      sed -e '1,$s/old string/new string/g' "${fname}" > "${myFileTmp}"
      # If you want to change back to the original file uncomment the line below
      # [ $? -eq 0 ] && mv "${myFileTmp}" "${fname}"
done

mcxalter(1)							  USER COMMANDS 						       mcxalter(1)

  NAME
      mcxalter - various network transformations

  SYNOPSIS
      mcxalter [-imx <fname> (specify matrix input)] [-abc <fname> (specify label input)] [-tab <fname> (use tab file)] [-o <fname> (output)] [-tf
      spec (apply tf-spec to input matrix)]

  DESCRIPTION
      This utility supplies various transformations of networks.

  OPTIONS
      -abc <fname> (label input)
	The file name for input that is in label format.

      -imx <fname> (input matrix)
	The file name for input that is in mcl native matrix format.

      -tab <fname> (use tab file)
	This option causes the output to be printed with the labels found in the tab file.  With -abc this option will, additionally, construct  a
	graph  only on the labels found in the tab file.  If this option is used in conjunction with -imx the tab domain and the matrix domain are
	required to be identical.

      -tf <tf-spec> (transform input matrix values)
	Transform the input matrix values according to the syntax described in mcxio(5).

      -o fname (output file)
	Output file.
