Adding an extension to a group of filenames
Hi -
I'm stuck. I have a group of text files created using the split command. My files have the names "projectaa", "projectab", "projectac", etc. What I want to do is add the extension ".txt" to each file. I think I've got part of a sed command together, but I'm stuck on my regex - I keep getting an error "Illegal variable name".
Here's the regex I created:
ls -d * | sed "s/^project[a-z][a-z]$/mv '&' \.txt/" | sh -v
Can anybody help me fix this? Or, offer an alternative way of renaming the files? I don't want to use the mv command by itself because each time I use split on a new text file, I won't know how many new files will be created.
Thanks!

putdgrp
putdgrp(1M) System Administration Commands putdgrp(1M)
NAME
putdgrp - edits device group table
SYNOPSIS
putdgrp [-d] dgroup [device...]
DESCRIPTION
putdgrp modifies the device group table. It performs two kinds of modification. It can modify the table by creating a new device group or
removing a device group. It can also change group definitions by adding or removing a device from the group definition.
When the command is invoked with only a dgroup specification, the command adds the specified group name to the device group table if it
does not already exist. If the -d option is also used with only the dgroup specification, the command deletes the group from the table.
When the command is invoked with both a dgroup and a device specification, it adds the given device name(s) to the group definition. When
invoked with both arguments and the -d option, the command deletes the device name(s) from the group definition.
When the command is invoked with both a dgroup and a device specification and the device group does not exist, it creates the group and
adds the specified devices to that new group.
OPTIONS
The following options are supported:
-d Delete the group or, if used with device, delete the device from a group definition.
OPERANDS
The following operands are supported:
dgroup Specify a device group name.
device Specify the pathname or alias of the device that is to be added to, or deleted from, the device group.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 Command syntax was incorrect, an invalid option was used, or an internal error occurred.
2 Device group table could not be opened for reading or a new device group table could not be created.
3 If executed with the -d option, indicates that an entry in the device group table for the device group dgroup does not exist and
so cannot be deleted. Otherwise, indicates that the device group dgroup already exists and cannot be added.
4 If executed with the -d option, indicates that the device group dgroup does not have as members one or more of the specified
devices. Otherwise, indicates that the device group dgroup already has one or more of the specified devices as members.
EXAMPLES
Example 1: Adding a new device group.
The following example adds a new device group:
example# putdgrp floppies
Example 2: Adding a device to a device group.
The following example adds a device to a device group:
example# putdgrp floppies diskette2
Example 3: Deleting a device group.
The following example deletes a device group:
example# putdgrp -d floppies
Example 4: Deleting a device from a device group.
The following example deletes a device from a device group:
example# putdgrp -d floppies diskette2
