If you sort your data, however, you can use the comm utility, which does not need to completely load either file into memory. Since the lines are in sorted order, it can tell when a line and when a line is skipped by whether the next line is greater or less or equal...
sort should be smart enough to process in blocks and not run out of memory. Be sure you have enough /tmp/ space, or redirect it to use another folder for temporary files where you have the room. See man sort for details.
Note that it might be possible to run comm once to get both sets of data, if only I knew what your data looks like -- which I still don't, after asking several times...

Hi, all:
I've got two folders, say, "folder1" and "folder2".
Under each, there are thousands of files.
It's quite obvious that there are some files missing in each. I just would like to find them. I believe this can be done by "diff" command.
However, if I change the above question a... (1 Reply)

ipmicmd
openipmicmd(1) An IPMI Command Interface openipmicmd(1)NAME
openipmicmd - An IPMI Command Interface
SYNOPSIS
openipmicmd [-k entry-to-execute] <connection parms>
DESCRIPTION
The openipmicmd program allows a user to execute direct IPMI commands. It can work with direct interface with the OpenIPMI driver or with
IPMI LAN interfaces.
OPTIONS -k entry-to-execute
Execute a single command an exit.
<connection parms>
The parameters for the connection depend on the connection type. These are all described in openipmi_conparms (7)
COMMANDS
Once up, you can execute commands in the user interface. Note that commands and responses are asynchronous, you issue a command and the
interface returns immediately. When the response comes back, it will be dumped on your console. That's a little strange looking, but IPMI
is asynchronous underneath. Note that the -k option is synchronous, it will wait for the response or a timeout before returning.
0f lun netfn cmd [data1 [data2 ...]]
Send a command to the BMC you are connected to.
channel [ipmb] IPMB-addr lun netfn [seq] cmd [data1 [data2 ...]]
Send a command to a device on the IPMB bus. The "ipmb" string is optional. The seq must be provided if the netfn is a response (an
odd number). It must be the same sequence number that came in on the command in the "Command Sequence = seq" part of the command.
channel 00 IPMB-addr lun netfn cmd [data1 [data2 ...]]
Send a broadcast command to a device on the IPMB bus.
channel lan handle remote-swid local-swid lun netfn cmd [data1 [data ...]]
Send a command to a device over a LAN channel. Note that this not the same as a LAN connection. This sends a message through a
local BMC to a remote system that is hooked up with a LAN connection.
test_lat count command
Executes the given commands (one of the previous commands) count times and gives the average time per command to execute. Note that
"count" is hexadecimal.
help Display some help.
regcmd netfn cmd
Register to receive the given command. If the driver receives an external command, it will print it out. This only works with sys-
tem interface connections, it will not work on LAN connections.
unregcmd netfn cmd
Remove a command registration.
SEE ALSO ipmi_ui(1), ipmilan(8), openipmi_conparms(7)KNOWN PROBLEMS
The asynchronous nature of the program can be annoying.
