This string is repetaed several times in the file, so I need to know how many times it appears in the file, this is the text files:
Create a file where you store the instances you are looking for like Strings.txt and create another file where you paste this script and name it String_Freq.awk

awk -f String_Freq.awk Strings.txt

strings.txt
ST*850*
ISA*00*
BEG*00*





String_Freq.awk
Code:
NR==FNR {words[++nwords]=$0;next}
{for(i=1;i<=NF;i++) freq[$i]++}
END {for(w=1;w<=nwords;w++)
{if (freq[words[w]]+0>0) print "Instances of " words[w] " : " freq[words[w]]+0}}

NAME
fontimage - produce a font thumbnail image SYNOPSIS
fontimage [--help] [--width num] [--height num] [--pixelsize num] [--text string] [--o outputfile] [--usage] [--version] fontfile DESCRIPTION
The program fontimage loads a font, which may be in any format fontforge(1) can read, and then produces an image showing representative glyphs of the font. OPTIONS
--help Provide a description with a list of the available options. --width num Specifies the width of the output image. If this is omitted the image will be as wide as necessary to display the text. --height num Specifies the height of the output image. If this is omitted the image will be as high as necessary to display the text. --pixelsize num Specifies the pixelsize used to display the text. This argument may be specified multiple times and each refers to any --text lines that follow it. --text string Specifies a line of text to be displayed. The string must be in UTF-8. This argument may be specified multiple times to provide several lines of text. If no --text arguments are supplied fontimage will examine the font, looking for various scripts it knows about, and will try to display something appropriate for each. -o outfile Specifies the output filename for the image. The type of image will be determined by the file's extension. Currently only ".bmp" and ".png" are recognized. If omitted fontimage will choose an output name based on the font's fontname field. --usage Display the usage description. --version Display the current version SEE ALSO
