multiple files with the same name grid_200001.grb2.nc with only one components changing and that is the month grid_200010.grb2.nc. I would like to use them all simultaneously as input files
An example of what I am hoping to achieve is
fname="grid_"
year="2010"
month="01 02 03 04 05 06 07 08 09 10"
ext="grb2"
end="nc"
for((y=$year;y<=$year;y++));
do
for m in $month
do
ifile=$fname$y$m.$ext.$end
>>merge $ifile $ifile ... ofile
example of the desired command i would like to have is
>> merge grid_200001.grb2.nc grid_200002.grb2.nc ....grid_200012.grb2.nc ofile
I would like all the files i have available as input files inputs at the same time
fname="grid_"
years=({2000..2010})
months=(01 02 03 04 05 06 07 08 09 10) ## ({01..10}) should be the same
ext="grb2"
end="nc"
shopt -s extglob
IFS='|' eval 'pattern="${fname}@(${years[*]})@(${months[*]}).${ext}.${end}"'
echo "pattern = ${pattern}" ## for curiosity.
files=($pattern) ## pathname expansion is sorted in Bash.
merge "${files[@]}" ofile
You can try this:
cat grid_2010[01][0-9].grb2.nc >> ofile
I'm not sure I understand the question exactly (edited thanks to your comments)
filenames=""
for year in $(seq 2000 2010)
do
for month in $(seq -w 0 10)
do
filename="grid_"$year$month".grb2.nc"
filenames=$filenames" "$filename
done
done
your_command $filenames
which may be what you need?
cat and wildcards is nice but would it keep the same order?
edited again:
But then, the wildcard choice is much simpler your_command grid_20[01][0-9][01][0-9].grb2.nc if you need them only in ascending order (will that always be the case with the wildcards?)
