Hey everyone,
Basically, all I'm looking for is a way to regex for not a certain string. The regex I'm looking to avoid matching is:
D222
i.e. an equivalent of:
awk '!/D222/'
The problem is that I use this in the following command in a Bash script:

matched string:root

Hi,
I'm trying to match the front and back of a sequence. It works when there is an exact match (obviously), but I need the regex to be more flexible. When we get strings of nucleotides sometimes their prefixes and suffixes aren't exact matches. Sometimes there will be an extra letter and... (2 Replies)

fs_cleanacl
FS_CLEANACL(1) AFS Command Reference FS_CLEANACL(1) NAME
fs_cleanacl - Remove obsolete entries from an ACL SYNOPSIS
fs cleanacl [-path <dir/file path>+] [-help] fs cl [-p <dir/file path>+] [-h] DESCRIPTION
The fs cleanacl command removes from the access control list (ACL) of each specified directory or file any entry that refers to a user or group that no longer has a Protection Database entry. Such an entry appears on the ACL as an AFS user ID number (UID) rather than a name, because without a Protection Database entry, the File Server cannot translate the UID into a name. Cleaning access control lists in this way not only keeps them from becoming crowded with irrelevant information, but also prevents the new possessor of a recycled AFS UID from obtaining access intended for the former possessor of the AFS UID. (Note that recycling UIDs is not recommended in any case.) OPTIONS
-path <dir/file path>+ Names each directory for which to clean the ACL (specifying a filename cleans its directory's ACL). If this argument is omitted, the current working directory's ACL is cleaned. Specify the read/write path to each directory, to avoid the failure that results from attempting to change a read-only volume. By convention, the read/write path is indicated by placing a period before the cell name at the pathname's second level (for example, /afs/.abc.com). For further discussion of the concept of read/write and read-only paths through the filespace, see the fs mkmount reference page. -help Prints the online help for this command. All other valid options are ignored. OUTPUT
If there are no obsolete entries on the ACL, the following message appears: Access list for <path> is fine. Otherwise, the output reports the resulting state of the ACL, following the header Access list for <path> is now At the same time, the following error message appears for each file in the cleaned directories: fs: '<filename>': Not a directory EXAMPLES
The following example illustrates the cleaning of the ACLs on the current working directory and two of its subdirectories. Only the second subdirectory had obsolete entries on it. % fs cleanacl -path . ./reports ./sources Access list for . is fine. Access list for ./reports is fine. Access list for ./sources is now Normal rights: system:authuser rl pat rlidwka PRIVILEGE REQUIRED
The issuer must have the "a" (administer) permission on each directory's ACL (or the ACL of each file's parent directory); the directory's owner and the members of the system:administrators group have the right implicitly, even if it does not appear on the ACL. SEE ALSO
