gdasearc08 not archiving correctly in bash

[SeanPFCasey]

I'm using the current develop branch on Orion with LOCALARCH="YES" and 80 ensemble members to allow for local archiving of tar files (to transfer to Niagara, then HPSS later). gdasarch, gfsarch, and gdasearc00-gdasearc07 all run as expected.

gdasearc08, however, does not archive the appropriate tar files. The following is noted in gdasearc08.log:

/work/noaa/aoml-osse/scasey/fv3develop20220921/global-workflow/jobs/rocoto/earc.sh: line 35: 08: value too great for base (error token is "08")

I have only seen this happen on Orion, but this is the only machine I have access to where I use bash, so it could happen elsewhere.

This occurs with a version of the develop branch checked out 20220921, and can be reproduced with minimal changes to config.base defaults in cycled mode:
CCPP_SUITE="FV3_GFS_v16"
imp_physics=11
NMEM_ENKF=80
HPSSARCH="NO"
LOCALARCH="YES"
ARCH_WARMICFREQ=1

See (on Orion) /work/noaa/aoml-osse/scasey/EXPDIR/test3/config.base for full settings.

In discussion with Kate and Walter, and testing on Orion, it was determined that this group-8 archival issue can be fixed with two changes to earc.sh:

Line 35: n=$((10#$ENSGRP))
Line 65: if [[ 10#$ENSGRP -gt 0 ]] && [[ $HPSSARCH = "YES" || $LOCALARCH = "YES" ]]; then

Without "10#" added before $ENSGRP, bash will interpret any number beginning with 0 as an octal, which only has values 0-7. Adding 10# to the beginning ensures $ENSGRP is treated as a decimal.
