Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

New (n permanent) Slackware 11 (ibare 2.4 kernel) user. A few questions regarding kernel upgrade/patch (my 1st):
1.Got these (only) 2 failures while patching the 220.127.116.11 kernel with this patch from bytesex.org: patch-2_4_26-kraxel_gz ( want aviosys 7134 TV Tuner pci card drivers, also driver for bttv cards )
1.(Stripping trailing CRs from patch.)
patching file drivers/media/video/bttv-driver.c
Hunk #10 FAILED at 258.
1 out of 15 hunks FAILED -- saving rejects to file drivers/media/video/bttv-driver.c.rej
patching file drivers/media/video/bttv-if.c
Hunk #9 FAILED at 150.
1 out of 9 hunks FAILED -- saving rejects to file drivers/media/video/bttv-if.c.rej
Opened .rej and .c files in kwrite (saw the previous formatted text) and added (in bttv-driver.c) :
.v4l2_id = V4L2_STD_PAL_N,
.name = "PAL-N",
/* PAL-N */
Also, bttv-if.c.rej( there were no red and blue lines) contents (There were very few differences in .c.rej and .c....On a hunch i opened patch-2_4_26-kraxel_gz in kwrite and saw that below lines, referring to same file were in red with a - sign):
*** 144,352 ****
So deleted all these lines starting from:
/* I2C functions ....
Added these 2 lines at the end since they were in patch-2_4_26-kraxel_gz (not red) and not in bttv-if.c:
Please comment on whether what i did above was correct or not.
2.Since i want to recompile the kernel ,i would like to know which (where) are the incremental patches which can be d/l and tranferred on a floppy. I have the patches: from patch-18.104.22.168 to patch-22.214.171.124. I suppose these patches can't be applied as they are not incremental patches (i.e.patch-126.96.36.199 can be applied only to 2.4.33 to bring it up to 188.8.131.52) ???
Read for 2.6 kernel u can go back and then do an upgrade (but how?)..ex.from 184.108.40.206 to 2.6.17 and then to 2.6.18. Is it possible for kernel to be upgraded to 2.4.34 using only incremental patches or is it better/less trouble to stick with 220.127.116.11/18.104.22.168? (have Internet access only at cybercafe)
Hunks usually get rejected because the code to replace is not in the place the patch says it is. Someitmes you have to manully insert those hunks -stuff with the '-' is what gets removed and stuff with '+' is what gets added. You can sometimes jiggle the line lumbers in the patch to do the same thing. Try using 'patch -l' to ignore minor white-space differernces.
Usually grepping for the leading line of each hunk in the source file will help you find where the code is intended to go:
Thanks gnashley.I tried with -l switch-same outcome. I am quite sure i got the "driver" file right.
Also patched kernel with patch-22.214.171.124 Deleted the .rej's)
