Error Message:

usr/bin/mv: 0403-027 The parameter list is too long

If you are dealing with a lot of files, you will sometimes hit the system limits for command lines. Here is an example of it:

Attachment: savea_20090901200021.log
/acct/vertex/backup_begin.sh[14]: /usr/bin/mv: 0403-027 The parameter list is too long.

How to modify the system parameter

# smitty chgsys

Then, in the list of system parameters, search for the ARG/ENV list size in 4K byte blocks:

Change / Show Characteristics of Operating System

Type or select values in entry fields.
Press Enter AFTER making all desired changes.

[MORE…9] [Entry Fields]
Amount of usable physical memory in Kbytes 32833536
State of system keylock at boot time normal
Enable full CORE dump false +
Use pre-430 style CORE dump false +
Pre-520 tuning compatibility mode disable +
Maximum login name length at boot time [9] +#
Stack Execution Disable (SED) Mode select +
NFS4 ACL Compatibility Mode secure +
ARG/ENV list size in 4K byte blocks [12] +# <===
CPU Guard enable +
Processor capacity increment 1.00
Partition is capped true
Partition is dedicated true

The default value of ARG/ENV list size in 4K byte blocks is 6. Slowly raise it (up to 1024 if needed) until your mv problem is solved!

The value change is immediate and will be applied the next time the machine is rebooted… It does not get any easier than this!

Another solution is to use the xargs command to pass each file, or directory, to the mv command one at a time.
