I've also reduced the quote-count to a sensible number - only those required. The batch command ECHO is used for echoing commands on/off and printing message to the console. Returning to your original, then - what you were doing is echoing the string ""parameter one"" into findstr - which doesn't end with ~ and hence would never be found.Īs I've posted, setting file_path with quotes surrounding the entire assignment clause ensures that the variable does not get set to (any trailing spaces on the line left by your editor) - which is a right cow to find the first time you encounter it (note that batch is very sensitive to stray spaces - you must omit them in a SET before the = else they get included in the variable-name and also after the = else they get included in the value assigned SET /A is a different animal - it tolerates spaces.) Since you don't say which match you want, it's not possible to say whether you actually want findstr "~$" (find ~ at end) or findstr /l "~$" (find "~$" somewhere) - or perhaps FIND "~$" may better suit your purpose ( FIND, not FINDSTR) You should also get a file named test. and you'll get this text on screen (we'll never get rid of this line on screen, as it is sent to the Console and cannot be redirected): This text goes to the Console.

By default, findstr matches on regular expressions - so findstr "~$" will match ~ at the end of the string, not ~$ anywhere within the string. Redirect 'all' output to a single file: Run: test.bat > test.txt 2>&1. 4 hours ago Batch PowerPoint File Converter is a unique tool used to reduce the manual work of. do (something & something else&if %errorlevel%=0 anotherthing)īit there's a nasty gotcha in this scheme. It is fast and easy to use, and as powerful as you need. When doing the 'else,' it must follow the close parenthesis. Also, this batch file has an else statement that prints if no matches were found. It prints any files found containing this string into the results.txt file. It utilises a flexible Regular Expression engine to enable you to create sophisticated searches, preview replace, perform batch operations, extract text from files and more. In the example below, this batch file searches for computerhope in any txt file in the current directory using the wildcards.

īUT this syntax doesn't work in a block statement like for. This powerful program enables you to instantly find and replace words and phrases across multiple files and folders.

Will ALWAYS trigger - the if errorlevel n syntax means if errorlevel is n OR GREATER THAN n To turn on the file contents indexing, follow these steps: In the Start menu, search for Indexing Options. The magic line you are looking for is if not errorlevel 1. Setting file_path using set FILE_Path="%~1" will work, BUT the variable file_path (variable names are case-insensitive) to ((the first parameter minus enclosing quotes) enclosed in quotes)Įchoing that version again enclosed in quotes (which doubles-up the quotes) into FINDSTR should do findstr's thing - and your object appears to be to find ~$ in the string (but you don't specify this explicitly)įINDSTR will dutifully report any matching string found and set errorlevel to 0 if found and 1 if not.
