Hi
I am trying to use this command:
egrep '^a{2,6}$' testexpr4D
to retreive lines with 2,3,4,5, or 6 a's in a file .
The file testexpr4D has entries like:
a
aa
aaa
aaaa
aaaaa
aaaaaa
123456
ABCDEF
I was expecting to see 5 lines in the output but nothing happens.
Can anyone help... (10 Replies)
I have a script that does the following. It searches a listing of directories with specific extensions and then formats a wc on those files. The code looks like this
find <directory> -name '*.js' -o -name '*.html' | awk '{print \"wc -l \"$1}' > file \n"
The result is a file with the "wc -l"... (7 Replies)

Experts:
I don't know that regular expressions will ever be easy for me, so if one of you guru's could help out, I'd appreciate it.
I'm trying to match a line in our syslog, but I can't figure out how to match a number inside a bracket. This is what I'm trying to match.

Hi,
I'm trying to validate if a string matches a regular expression, but it is not working. Am I missing something? Do I need to scape any of the characters?
if echo 'en-GB' | egrep '({1,8})(-{1,8})*' >/dev/null; then
echo Valid value
fi
Thanks in advance (6 Replies)

Hi,
I have a question, during my readings it appears that these two variables in the snippet below need to be on the same line to return a “true” answer and listed in the output otherwise it won’t be returned. How can I write this snippet to make it return a “true” if those two variables are on... (6 Replies)

run-parts
RUN-PARTS(8) System Manager's Manual RUN-PARTS(8)NAME
run-parts - run scripts or programs in a directory
SYNOPSIS
run-parts [--test] [--verbose] [--report] [--lsbsysinit] [--regex=RE] [--umask=umask] [--arg=argument] [--exit-on-error] [--help] [--ver-
sion] [--list] [--reverse] [--] DIRECTORY
run-parts -V
DESCRIPTION
run-parts runs all the executable files named within constraints described below, found in directory directory. Other files and directo-
ries are silently ignored.
If neither the --lsbsysinit option nor the --regex option is given then the names must consist entirely of ASCII upper- and lower-case let-
ters, ASCII digits, ASCII underscores, and ASCII minus-hyphens.
If the --lsbsysinit option is given, then the names must not end in .dpkg-old or .dpkg-dist or .dpkg-new or .dpkg-tmp, and must belong to
one or more of the following namespaces: the LANANA-assigned namespace (^[a-z0-9]+$); the LSB hierarchical and reserved namespaces
(^_?([a-z0-9_.]+-)+[a-z0-9]+$); and the Debian cron script namespace (^[a-zA-Z0-9_-]+$).
If the --regex option is given, the names must match the custom extended regular expression specified as that option's argument.
Files are run in the lexical sort order (according to the C/POSIX locale character collation rules) of their names unless the --reverse
option is given, in which case they are run in the opposite order.
OPTIONS --test print the names of the scripts which would be run, but don't actually run them.
--list print the names of the all matching files (not limited to executables), but don't actually run them. This option cannot be used with
--test.
-v, --verbose
print the name of each script to stderr before running.
--report
similar to --verbose, but only prints the name of scripts which produce output. The script's name is printed to whichever of stdout
or stderr the script first produces output on.
--reverse
reverse the scripts' execution order.
--exit-on-error
exit as soon as a script returns with a non-zero exit code.
--lsbsysinit
use LSB namespaces instead of classical behavior.
--new-session
run each script in a separate process session. If you use this option, killing run-parts will not kill the currently running
script, it will run until completion.
--regex=RE
validate filenames against custom extended regular expression RE. See the EXAMPLES section for an example.
-u, --umask=umask
sets the umask to umask before running the scripts. umask should be specified in octal. By default the umask is set to 022.
-a, --arg=argument
pass argument to the scripts. Use --arg once for each argument you want passed.
-- specifies that this is the end of the options. Any filename after -- will be not be interpreted as an option even if it starts with
a hyphen.
-h, --help
display usage information and exit.
-V, --version
display version and copyright and exit.
EXAMPLES
Print the names of all files in /etc that start with `p' and end with `d':
run-parts --list --regex '^p.*d$' /etc
