Editing I/O API file dates only

I/O API
1

I just want to edit the MCIPv4.5 output files in I/O API format such that year 2000 becomes 2005 and everything else stays the same. What are some ways to tackle this problem?

2

Trying to edit in place will mess up the internal data structures. Instead, use M3Tools program m3tshift: see https://www.cmascenter.org/ioapi/documentation/all_versions/html/M3TSHIFT.html

m3tshift of I/O API v3.1 didn’t work for me - it kept creating a new file with the same old date (basically not replacing 2000 with 2005)!

I just re-checked and it works for me. What version do you have (do ident which m3tshift)?
The current version has

 $Id: m3tshift.f90 117 2019-06-15 14:56:29Z coats $
5

When I typed the command ‘ident m3tshift’, I got:

 $Id:: m3tshift.f 79 2014-12-12 16:28:01Z coats             $
 $Id:: init3.F 321 2016-02-26 16:00:20Z coats                $

This version is at least 4 versions (jun152019, dec12017, sep092017, jun142016) out-of-date. You may want to update… everything.

Looks like only v3.2 is on github, I will download the tar-zip of v3.1 directly at https://www.cmascenter.org/ioapi/download/ioapi-3.1.tar.gz

Both of these versions should work correctly, unless you’re doing something like

setenv PROMPTFLAG N

I’d need to see a complete log to help any further.

In a command line interactive execution of the I/O API tool m3tshift, I just press the ‘enter’ key to accept default value, but in a shell script version of the same tool in UNIX, what should I write in the code that indicates ‘enter’ key equivalent to accept the default values? A blank is not working for me.

I normally do something like the following (in this example, from a script for m3probe, which has a somewhat-complicated set of prompts and defaults) [where I’m having to use backslash-poundsymbol to make this editor happy;-( ]

set UI    = /tmp/m3probe.$$

echo "Yes         " >&  ${UI}          \# continue with the program
echo "            " >>  ${UI}          \# default starting date
echo "            " >>  ${UI}          \# default starting time
echo "            " >>  ${UI}          \# default ending   date
echo "            " >>  ${UI}          \# default ending   time
echo "            " >>  ${UI}         \ # default time step
echo "${VARIABLE} " >>  ${UI}         \ # name for variable to be probed
echo "${POINT}    " >>  ${UI}         \ # number for stream-reach to be probed
echo "0           " >>  ${UI}          \# end list of points

time ${pgm} < ${UI}
set foo = ${status}
if ( ${foo} != 0 )  echo "ERROR ${foo} on program m3probe"
exit ( ${foo} )

Thanks - I use a tcsh shell, and some changes worked for me:

mkdir -p temp_files
set UI = $cwd/temp_files/temp_response_m3tshift_2may2020.${source_YYYYMMDD}.${SECTOR}.$$
echo INFILE >>  ${UI}               \ 
echo "" >>  ${UI}                   \ 
echo "" >>  ${UI}                   \ 
echo ${YYYYDDD_target} >>  ${UI} \ 
echo "" >>  ${UI}                   \ 
echo "" >>  ${UI}                   \ 
echo "" >>  ${UI}                   \ 
echo OUTFILE >>  ${UI}
