Hi Eagl€, you probably mean:
egrep '>|^[AGC]*$' infile
But I do not think that works here, since then you filtering on the fact that there happens to be no T present on the lines with 3 characters,...

egrep '>|^[A,G,C]*$' infile

egrep '^>|^[A-Z]{3}$' infile
egrep '^(>|[A-Z]{3}$)' infile

while read pattern; do
grep "^$pattern [0-9]" file1
done <file2

egrep '>|^[A-Z][A-Z][A-Z]$' infile

awk '/^\[/{s+=1;next}{if (s!=0) print s;s=0}' file

$ sed '/^DEFINITION/,/^ORIGIN/d' input | sed '/LOCUS /s//>/' | awk '/^>/{print $1} NR>1'
