Script to pull certain characters from a filename and use in a variable?
Hi All,
I have a script that runs another script in batch mode for a folder of files. The script needs the input file name and a 4-letter abbreviation for that file (the -taxon= flag).
Code:
for myfile in *.fas
do
myscript.pl -sequence_file=$myfile -taxon=**needs to be a 4-letter abbreviation**
done
The files are all named as such (Genus_species):
Lottia_gigantea.fas
Aplysia_californica.fas
Mytilus_edulis.fas
I would like the taxon flag to be the first letter of the genus and the first three letters of the species in all caps like this:
myscript.pl -sequence_file=Lottia_gigantea.fas -taxon=LGIG
myscript.pl -sequence_file=Aplysia_californica.fas -taxon=ACAL
myscript.pl -sequence_file=Mytilus_edulis -taxon=MEDU
Can anyone help me out? Do I need to use xargs for this?
