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}}

another way by gawk

Code:
gawk -F "ST\\\*850\\\*" '{print NF-1}' infile

jum mcnamara your code give errors:
Syntax Error The source line is 10.
The error context is
>>> END <<< {print "Found ", cnt, " Times" }
awk: 0602-502 The statement cannot be correctly parsed. The source line is 10.
awk: 0602-540 There is a missing } character.

my grep command does not have -o option

check my another reply, if your awk is GAWK, it should work for you.
