anyone know a commandline tool to add a line of text to end of a text file?
e.g.
addlinetofile.exe "c:\notes.txt" "this is a line of text to add"

i could code this easily enough and it would probably be 2 lines of perl but i wonder if anyone knows any existing tools to do this, maybe with some extra functionality?

thanks dajo, i'm always overlooking the simplest solutions :)

but still i can't help but wonder if there are some existing tools that offer some more functionality i might not have even thought of yet..

   synchronised line appendage from other files, input/output line
   selection by line numbers or passwords, spaces/empty lines
   absorption, filewise update or renaming, line width imposition and

   lines can also be taken from the command line aline.

See Edlin Command Help

There is also mouse driven DOS command Edit

Stefan mentioned SED and AWK, which are both command-line text manipulation tools.  SED is the simplest, and is best used for regular expression search and replace.  AWK is its own little programming language, and is a more powerful than SED, but much lighter than Perl.

I spent a lot of time exploring text manipulation tools a few years back.  I ended up using AWK and Perl for most things, but then I found Datamystic's TextPipe Pro (shareware, $299) http://snipurl.com/leapfrog_textpipe, for it's power and ease of use.  I became such a fan of the product that I have since become a reseller.

I might be able to work out a discount deal on TextPipe for DonationCoder members only... Mouser, I will contact you about this offline.

textpipe really looks like a great application; probably even with a real discount it would be out of range for most of us but still any discount for our members would be welcome, and you might just make someone's day :)  :up:

Uh, I ended up feeling that SED was a bit like trying to use an early programmable calculator, and that AWK was actually easier simply because it's more like a recognisable language.  Eric Pement has a good Web site for both and also for the kind of command line tools Stefan mentioned (go to his SED page and keep paging down);

Eric Pement's  Web site; SED, Awk, Perl, search-and-replace utilities including useful supplementary information, help and workarounds for Minitrue / MT / MTR / Ministry of Truth under Windows 2000 / Win2K.

One set of Unix utils ported to Windows and including CAT is at
http://unxutils.sourceforge.net

Mouser, here's the online help for the Berkley utils version of cat, more informative than the GNU equivalent;

=== begin quote ===
usage: berkcat file(s)
Concatenates the file(s) to the standard output.
If one of the files is `-', the standard input is used.
No options.
Example:
       C:>cat - file1 >newfile
       this is the new first line
       and this is the second.
       ^Z
       C:>mv newfile file1

This is a way to add 2 lines to the beginning of file1 without using
an editor.

To append file1 at the end of file2, type
        cat file1 >> file2
=== end quote ===

Thanks rjbull,
that's very helpfully.

I played around a bit (i like unix tools but i have mostly plain dos commends only):

>To append file1 at the end of file2, type
>        cat file1 >> file2
C:\>type file1 >>file2

To append a line of text at the end of file2, type
C:\>echo "some text" >>file2

To append a line of text at the beginn of file3, type
C:\>echo "some text" >tmpfile && type file3 >> tmpfile && ren tmpfile file3

Is it possible to append text to a file without recreating the file? I am just afraid that that would change creation modification dates of the file, and that info is much needed for the file I am working with.

kartal: if you use something like "echo blah >> file.txt", the last-modified will be changed, creation date shouldn't... also, not all tools will be good for this, I'm afraid SED and AWK would read in the entire existing file before appending the line? Bad if you're dealing with huge files :)

I do not have any problem with modification date. But I hate to see that creation date has changed.

It works amazing. But I am wondering if it is possible to remove formatting or change the formatting in the code?

I was looking for text manipulation software and found this link

It's a lot of free mainly stuff and with programs like

http://www.sac.sk/files.php?d=16&l=I

   INI v1.01 - Util to provide access to INI-files from the command line

May be useful.

I continue
