rubin -- could you explain the pipe and stuff?
I don't see why you left off the < on the end-of-line expression.
or what the question mark is doing...
Thanks,
Already explained perfectly by Gunther. The only thing I'd add is that lookahead-lookbehind are zero-width assertions, meaning that they don't match characters, but rather define positions where the pattern is located ( in this example, the pattern is airplane ), same concept as the anchors ^ and $, they define positions but don't match characters per se. It's a powerful and very useful concept.
Hello.
I have a dir of 1500+ dir. In these dirs is a file host, with a tag <x_tag>.
I need to :
1. grep for all dir that contain this host file that contain <x_tag>
2. print a list of these host files containing <x_tag>
is this better to egrep this? (5 Replies)

find . -name "*" | xargs grep "Smith"
Let me explain. I'm at a top level and need to know all the names of the files that... (6 Replies)
I've got this command that I've been using to find strings on the same line, say I'm doing a search for name:
find . -name "*" | xargs grep -i "Doe" | grep -i "John" > output.txt
This gives me every line in a file that has John and Doe in it. I'm looking to add a OR operator for the second... (5 Replies)

fnmatch
fnmatch(3C)fnmatch(3C)NAME
fnmatch() - match filename patterns
SYNOPSIS DESCRIPTION
performs pattern matching as described in regexp(5) under By default, the rule qualifications for filename expansion do not apply; i.e.,
periods (dots) and slashes are matched as ordinary characters. This default behavior can be modified by using the flags described below.
The flag argument modifies the interpretation of pattern and string. If which is defined in is set in flag, a slash character in string
must be explicitly matched by a slash in pattern; it cannot be matched by either the asterisk or question mark special characters or by a
bracket expression.
If is set in flag, a leading period must be explicitly matched. It will not be matched by a bracket expression, question mark or asterisk.
By default, a period is leading if it is the first character in string. If is set in flag, a period is leading if it is the first charac-
ter in string or immediately follows a slash.
If is not set in flag, a backslash character in pattern followed by any other character matches that second character in string. In par-
ticular, matches a backslash in string. If is set, a backslash character is treated as an ordinary character.
If flag is zero, the slash character and the period are treated as regular characters. If flag has any other value, the result is unde-
fined.
RETURN VALUE
If string matches the pattern specified by pattern, returns zero. Otherwise, returns non-zero.
EXAMPLE
The following excerpt uses to check each file in a directory against the pattern
pattern = "*.c";
while(dp = readdir(dirp)){
if((fnmatch(pattern, dp->d_name,0)) == 0){
/* do processing for match */
...
}
}
