W. & K. . The one in the book doesn't come with most unix systems. You have to buy it from ATT. They also have a nifty tool I wish we could get which takes awk programs and writes c code. I haven't found a way to get older awk to read more than one file. Mostly I get around this by using multiple awk programs that pipe output into each other. Booker C. Bense /* benseb@grumpy.sdsc.edu */ grep ?!$ Isn't that something that sticks to your shoes ? %-) &-) 8-)

If you want no action, use ";", as in gawk ' { while (getline <"lettre" > 0 ) ; } ' Additionally, if you are using Sun awk, I don't think you can use input redirection with getline. The following runs without error in Sun awk. awk ' { while (getline > 0 ) ; } ' Gawk is available by anonymous ftp from prep.ai.mit.edu (and many sites in Europe as well.) I believe that to compile gawk, it is helpful to get "bison" and "gcc", which are available from the same place.

>Additionally, if you are using Sun awk, I don't think you can use input >redirection with getline. The following runs without error in Sun awk. "Sun awk" should probably be replaced by "old awk" in the above. "Sun awk" is basically either BSD "awk" (which is basically V7-addendum-tape "awk") prior to SunOS 3.2, or S5R2 "awk" in 3.2 and later (AT&T sped it up a fair bit after the V7 addendum tape version came out). (The only Sun additions are minor null-pointer-dereferencing fixes and, as I remember, a tweak to allow "-" to stand for "standard input" when used as a program file name.) GNU "awk" ("gawk") implements "new awk", which is the "awk" described by the AWK book; AT&T also has a "new awk" implementation, available in S5R3.1 and later and also available from the AT&T Toolchest. SunOS 4.1 has AT&T's S5R3.1 "new awk" implementation (again, with null-pointer-dereferencing fixes; too bad the damn 3B2 ABI for S5R4 doesn't forbid location 0 being part of the address space, if it did maybe all those frigging null pointer dereferences in the porting base source would get FIXED).
