Deleting by ID
Need to delete records from a text file. Very new to this and am using pico. The only way i can think of doing this is to generate an ID for every record then tell it to delete that particular ID. First question is how if possible do i give each entry an ID number, the second is would this code work to delete an ID entry
sed '/.*ID.*/d' list.txt > list.txt
Any other suggestions on ways items can be deleted from a text file?
Thanks for your help

Hello,
How would one delete every other two lines using VI? For example, I have the following 8 lines:
Line1

And wish to only delete lines 3-4 and 7-8. Is there a certain pattern which would make this easier?
Thank you,

pts_delete
PTS_DELETE(1) AFS Command Reference PTS_DELETE(1)
NAME
pts_delete - Deletes a Protection Database entry
SYNOPSIS
pts delete -nameorid <user or group name or id>+
[-cell <cell name>] [-noauth] [-localauth]
[-force] [-help]
pts d -na <user or group name or id>+
[-c <cell name>] [-no] [-l] [-f] [-h]
DESCRIPTION
The pts delete command removes each entry specified by the -nameorid argument from the Protection Database. Deleting entries affects other
parts of the system in various ways:
o Deleted users and groups still appear on access control lists (ACLs), but are listed by AFS UID or GID rather than by name, because
there is no longer an associated name to which to translate the ID. To remove these obsolete entries from ACLs, use the fs cleanacl
command.
o Deleting a user or machine's entry removes it from the membership list of any group to which it belonged.
o Deleting a group entry removes it from the membership list of any user or machine entry that belonged to the group, and also increments
the group-creation quota of the group's creator by one, even if the creator no longer owns the group.
To remove a user or machine from a group without actually deleting the entry, use the pts removeuser command.
OPTIONS
-nameorid <user or group name or ID>+
Specifies the name or AFS UID of each user, the name or AFS GID of each group, or the IP address (complete or wildcard-style) or AFS
UID of each machine entry to delete. It is acceptable to mix users, machines, and groups on the same command line, as well as names (IP
addresses for machines) and IDs. Precede the GID of each group with a hyphen to indicate that it is negative.
-cell <cell name>
Names the cell in which to run the command. For more details, see pts(1).
-force
Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the
first error.
-help
Prints the online help for this command. All other valid options are ignored.
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or
-noauth options. For more details, see pts(1).
-noauth
Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1).
EXAMPLES
The following example deletes the user entries "pat" and "terry":
% pts delete pat terry
The following example deletes the Protection Database entry of the group with AFS GID -215.
% pts delete -215
PRIVILEGE REQUIRED
The issuer must belong to the system:administrators group to delete user and machine entries. To delete group entries, the issuer must
either own the group or belong to the system:administrators group.
