grep or find ?
I have a file called 'test.txt' that contains alphanumeric charecters.

The file contains the word 'SBE' followed by other alphabets many times. For example, the file will contain: SBE334GH and also will have SBE77Y8I.

When i do grep 'SBE*' test.txt - it outputs the entire file.

Can you tell which way to grep or use find perhaps to only show the words starting with SBE ?

Thanks

Try:
Code:
grep -oE 'SBE[^ ]*' test.txt

Code:
awk ' /SBE/ {for(i=1;i<=NF;i++) {if(index($i,"SBE")==1) {print $i  }  }  }  {next} ' inputfile

Thanks but now it is showing stuff after the comma. For example, i get this now:

SBE98JKU, OIX
SBE45T6Y, OIW

how to get only the SBE string and nothing else after it?
