Re: ctrl-z blues
Hi Squashman! Speaking of Line Feeds, I stumbled across some bizarre behaviour in my tests. Create a test file called hi.txt with your favourite text editor: <255><254>hi there<SUB><CR><LF> The first two characters in the file are ASCII 255 and 254. This is known as the Byte Order Mark (BOM) and is ...

Re: ctrl-z blues
Hi Penpen! Thanks for your reply. You were right about saving the file as Unicode (UTF-16). Everything works fine when I do this. SUB doesn’t cause any problems. But I think type is the stumbling block. This works… cmd /d /u /c type unicode.txt > uni.out.txt but this doesn’t: cmd /d /u /c type ansi....

Re: Change in date input
Hi mor.bas!
Use Carlos’s pure Batch getDate function to acquire the date in locale-independent form. Once you have that nailed down, you can use xcopy’s /d switch to validate dates n days ago/from now as detailed in Paul Tomasi’s Validating Dates article.
HTH!

Re: ctrl-z blues
Me Again! Thanks aGerman for your suggestion. There was a recent discussion here about using set /p to slurp up long lines 1021 characters at a time. Dave Benham concluded that the method was “lossy” if the line had control characters at the end. Made for interesting reading all the same… And thanks...

Re: ctrl-z blues
Hi Again, Thanks for the replies. The Choice Function thread aGerman pointed to was riveting. How did I miss that? But I’m trying to find a way to use type with cmd /d /u /c so I can read every character in a file one by one. The only thing stopping me is Ctrl-Z (SUB). If the input file contains a S...

ctrl-z blues
Hello All! Imagine a test file called hi.txt with the contents “hi there” (no quotes and no newline). It’s possible to print out the characters of the file one by one using a little trick I learnt from Judago : cmd /d /u /c type hi.txt | find /v "" h i t h e r e This would be extremely use...

Re: FTP Download only new files any file type
Hi Thlockler, Sorry for not replying sooner. I was on my holidays! Anyways, I don’t fully understand your question. The script makes two connections to the ftp host. On the first pass, it builds a list of all files matching the findstr pattern. On the second pass, it downloads only those files that ...

reverse string without goto
Building on what I learnt from Dave Benham’s demonstration of escaping special characters inside a for /f loop’s in (…) clause , and Aacini’s use of a for /l loop called by a cmd subshell to emulate a while loop , I’ve cobbled together an alternative method for reversing a string that does not requi...

Re: vagaries of for /f loops
Thanks Penpen and Dave! In the second example, multiple parameter separators (, ; = <SP> and <TAB>) are indeed replaced with a single space… but not dots. Note that if you quote the string, any leading whitespace and the opening quote itself will be stripped away and the rest of the string will be d...

Hi All!
Below is an alternative technique for trimming leading and trailing spaces and tabs from a string…
Edit: Please read revised code.

vagaries of for /f loops
Dear DosTips, I came across something puzzling while researching an alternative method of trimming whitespace (spaces and/or tabs) from the head and tail of a string. To trim any whitespace on the left of a string, simply do this: for /f "tokens=*" %%a in ("%string%") do set &quo...

Re: Some Explaination on these
Hello Flora! This line of code is a clever but ugly hack: SET v=%v:;=&rem.% It has the effect of discarding everything in the string after the first occurrence of semi-colon (inclusive). It is the opposite of: SET v=%v:*;=% which removes everything before the first occurrence of a semi-colon (se...
