Solve : find and findstr help? |
| Answer» <html><body><br/>"find" does partly what I want, and "findstr" does partly what I want. But neither one separately provides fully what I want to accomplish.<br/><br/>I want to count the occurrences of string1 in a text file output.txt, only if the string is at the beginning of the line. I do not want to see the lines scroll on the screen, only the number of occurrences.<br/><br/>Then I want to count the occurrences of string2 in the same file output.txt, again only at the beginning of the line and displaying only the count.<br/><br/>Then I want to compare the two counts, either with a visual check on the screen or with the comp command if I chose to send the results to two text <a href="https://interviewquestions.tuteehub.com/tag/files-20889" style="font-weight:bold;" target="_blank" title="Click to know more about FILES">FILES</a>. If the two counts are the same, I am okay; if not, echo an error message.<br/><br/>Is there a <a href="https://interviewquestions.tuteehub.com/tag/way-246442" style="font-weight:bold;" target="_blank" title="Click to know more about WAY">WAY</a> to pipe find and findstr together in one statement?<br/><br/>I can solve the problem with the following steps, but this seems like double work for each search:<br/><br/><br/>findstr/b "string1" output.txt > count1.txt<br/>findstr/b "string2" output.txt > count2.txt<br/>find/c "string1" count1.txt<br/>find/c "string2" count2.txt<br/><br/><br/>Thanks in advance.
