Hi, I am trying to check that a file does not contain lines with terminating tabs (see attached). The file is about 1000 lines long in the format of <word><tab><tab><word><CR>, yet my "grep" finds 5 lines with terminating tabs. I checked the file with a binary editor - nope!
all the info (input, output, version, and one "good" line for comparison) is included in the attached file, which also appears below. I run the same test on Ubantu and on SuSE 9.3 WITH THE SAME RESULTS (i.e. the same 5 lines are WRONGLY identified!) I would appreciate your feedback Meir Razy [EMAIL PROTECTED] NorthSide Inc start of input file ----------------------- (a "good" line) association consorting (the wrong lines) attachment attaching attainment achieving attrition rubbing personification attributing pluralization attributing ----------------------- end of input file the command: \cygwin\bin\grep -n "[a-z]*\t\t[a-z]*\t" input.txt command output: ---------------- 5:attachment attaching 6:attainment achieving 7:attrition rubbing 8:personification attributing 9:pluralization attributing end of command output ---------------- Version: -------- Report bugs to <[email protected]>. grep (GNU grep) 2.5.1 Help: ----- Copyright 1988, 1992-1999, 2000, 2001 Free Software Foundation, Inc.

Search for PATTERN in each FILE or standard input. Example: grep -i 'hello world' menu.h main.c Regexp selection and interpretation: -E, --extended-regexp PATTERN is an extended regular expression -F, --fixed-strings PATTERN is a set of newline-separated strings -G, --basic-regexp PATTERN is a basic regular expression -P, --perl-regexp PATTERN is a Perl regular expression -e, --regexp=PATTERN use PATTERN as a regular expression -f, --file=FILE obtain PATTERN from FILE -i, --ignore-case ignore case distinctions -w, --word-regexp force PATTERN to match only whole words -x, --line-regexp force PATTERN to match only whole lines -z, --null-data a data line ends in 0 byte, not newline Miscellaneous: -s, --no-messages suppress error messages -v, --invert-match select non-matching lines -V, --version print version information and exit --help display this help and exit --mmap use memory-mapped input if possible Output control: -m, --max-count=NUM stop after NUM matches -b, --byte-offset print the byte offset with output lines -n, --line-number print line number with output lines --line-buffered flush output on every line -H, --with-filename print the filename for each match -h, --no-filename suppress the prefixing filename on output --label=LABEL print LABEL as filename for standard input -o, --only-matching show only the part of a line matching PATTERN -q, --quiet, --silent suppress all normal output --binary-files=TYPE assume that binary files are TYPE TYPE is 'binary', 'text', or 'without-match' -a, --text equivalent to --binary-files=text -I equivalent to --binary-files=without-match -d, --directories=ACTION how to handle directories ACTION is 'read', 'recurse', or 'skip' -D, --devices=ACTION how to handle devices, FIFOs and sockets ACTION is 'read' or 'skip' -R, -r, --recursive equivalent to --directories=recurse --include=PATTERN files that match PATTERN will be examined --exclude=PATTERN files that match PATTERN will be skipped. --exclude-from=FILE files that match PATTERN in FILE will be skipped. -L, --files-without-match only print FILE names containing no match -l, --files-with-matches only print FILE names containing matches -c, --count only print a count of matching lines per FILE -Z, --null print 0 byte after FILE name Context control: -B, --before-context=NUM print NUM lines of leading context -A, --after-context=NUM print NUM lines of trailing context -C, --context=NUM print NUM lines of output context -NUM same as --context=NUM --color[=WHEN], --colour[=WHEN] use markers to distinguish the matching string WHEN may be `always', `never' or `auto'. -U, --binary do not strip CR characters at EOL (MSDOS) -u, --unix-byte-offsets report offsets as if CRs were not there (MSDOS) `egrep' means `grep -E'. `fgrep' means `grep -F'. With no FILE, or when FILE is -, read standard input. If less than two FILEs given, assume -h. Exit status is 0 if match, 1 if no match, and 2 if trouble.
