How to zip file one by one thru command line

[mkn]

Hi

I am having trouble to managing my disk space.

Currently i am getting file in following format.

a_011209.txt
a_021209.txt
b_011209.txt
b_021209.txt

I want to create a batch file where it will prompt me to change the date from 011209( DDMMYY format) to 021209 and then compress these files one by one.

Thanks in advance for your help.

C:\>compact  /?
Displays or alters the compression of files on NTFS partitions.

COMPACT [/C | /U] [/S[:dir]] [/A] [/I] [/F] [/Q] [filename [...]]

  /C        Compresses the specified files.  Directories will be marked
            so that files added afterward will be compressed.
  /U        Uncompresses the specified files.  Directories will be marked
            so that files added afterward will not be compressed.
  /S        Performs the specified operation on files in the given
            directory and all subdirectories.  Default "dir" is the
            current directory.
  /A        Displays files with the hidden or system attributes.  These
            files are omitted by default.
  /I        Continues performing the specified operation even after errors
            have occurred.  By default, COMPACT stops when an error is
            encountered.
  /F        Forces the compress operation on all specified files, even
            those which are already compressed.  Already-compressed files
            are skipped by default.
  /Q        Reports only the most essential information.
  filename  Specifies a pattern, file, or directory.

  Used without parameters, COMPACT displays the compression state of
  the current directory and any files it contains. You may use multiple
  filenames and wildcards.  You must put spaces between multiple
  parameters.

C:\>type  press.bat

Code: [Select]

@echo off

sed s/011209/021209/  datfile.txt


sed s/011209/021209/  datfile.txt  |  compact /cC:\>press.bat
a_021209.txt
a_021209.txt
b_021209.txt
b_021209.txt

 Setting the directory C:\ to compress new files [OK]

 Compressing files in C:\

-------------------------
rem Uncompress
rem C:\>sed s/011209/021209/  datfile.txt  |  compact  /u

I believe my sed version is for 32-bit and the creation date is 2005.

The simple substitution(s) of one pattern in a file name for different pattern seems to work ok.

sed s/011209/021209/  datfile.txt

p.s. I have not used 64-bit
