The ext2 tools consist of the following programs: E2CAT analogous to the Linux cat command E2CD analogous to the Linux cd command E2CP analogous to the Linux cp command E2LS analogous to the Linux ls command E2PART lists hard disk partitions E2PWD analogous to the Linux pwd command All these programs have been compiled with GCC and require the GO32 DOS extender in order to execute. There are currently no programs for writing to an ext2 file system and probably never will be unless someone else would care to make them. The programs are distributed in both binary and source code form. COPYRIGHT --------- The ext2 tools are copyright (C) 1995 Claus Tondering (ct@login.dknet.dk). Note: The ext2fs routines are copyright (C) 1993, 1994 Theodore Ts'o. For further copyrights, see the source code files. The ext2 tools may be redistributed under the terms of the GNU General Public License, which is included in the file called COPYING. For your convenience the GO32 program has been included in this distribution. It is part of the DJGPP distribution, which can be obtained by anonymous FTP from oak.oakland.edu in the directory /SimTel/msdos/djgpp. DISCLAIMER ---------- This is free software.

BASIC PRINCIPLES ---------------- Before you use the ext2 tools, you must set the environment variable E2CWD using a statement similar to the following: SET E2CWD=129:5 or SET E2CWD=129:5:234 The three numbers after the equals sign are interpreted thus: The first number (129 in the above example) identifies the physical disk on which the ext2 file system is located. The number is used as the second parameter to the DOS biosdisk() routine. Typical values are: 0 for A: disk 1 for B: disk 128 for first hard disk 129 for second hard disk (Your BIOS may use different values, especially if you have an SCSI drive.) The second number (5 in the above example) is the number of the disk partition on which the ext2 file system is located. This number is typically part of the Linux file name for the disk device. If, for example, you are used to referring to the disk as /dev/hdb5 under Linux, the partition number is 5. The E2PART program can help you identify the partitions. The third number is the inode number of the directory that is to be your current working directory. If this number is omitted, 2 (the root inode number) is used. If you don't know what an inode is, don't worry. Just omit the final number from E2CWD. Note: File names starting with / will be interpretet relative to the root directory on the particular disk identified by the E2CWD environment variable. None of the programs support wildcards. Be sure to have the GO32.EXE program somewhere in your PATH. E2CAT ----- SYNOPSIS E2CAT [-bt] pathname DESCTIPTION The E2CAT program will copy the contents of the file identified by ext2 pathname to the standard output. The following options are available: -b Binary mode. No translation performed. -t Text mode (default). LF translated to CR/LF. E2CD ---- SYNOPSIS E2CD pathname DESCRIPTION The pathname must identify an ext2 directory. That directory is made the current working directory. NOTE E2CD is a .BAT file that creates another .BAT file (called ___E2CD.BAT) that modifies the E2CWD environment variable. It then executes ___E2CD.BAT and deletes it. (So beware if you alread have a file called ___E2CD.BAT.) If you are using 4DOS, add the /Q switch to the DEL command in E2CD.BAT. E2CP ---- SYNOPSIS E2CP [-bt] file1 file2 DESCTIPTION The E2CP program will copy the contents of the file identified by ext2 pathname 'file1' to the MSDOS file 'file2'. The following options are available: -b Binary mode (default). No translation performed. -t Text mode. LF translated to CR/LF. E2LS ---- SYNOPSIS E2LS [-adiltr] pathname DESCRIPTION The pathname must identify an ext2 directory or file. The E2LS program provides a list of the contents of that directory in a manner similar to the Linux ls program. The following options are supported: -a Include file names starting with . in listing. -d List only pathname, even if it is a directory. -i Include inode number in listing. -l Produce a long listing. -t Sort by modification time. -r Reverse the sort order. E2PART ------ SYNOPSIS E2PART diskno DESCRIPTION The E2PART program lists the partitions that are available on a particular physical disk. This program does not use the E2CWD environment variable, instead the disk number is given as an argument to the E2PART program. BUGS The program is not very good at identifying MSDOS file systems. E2PWD ----- SYNOPSIS E2PWD DESCRIPTION The E2PWD program prints the current directory. HOW TO CONTACT THE AUTHOR ------------------------- The author can be contacted by e-mail at ct@login.dknet.dk.
