Verifying sting format in bash
Hello,
This one has me stumped, although I suspect it might be easy. I have a file and need to split the entries into two varaibles. The format for a positive is 'AANNNN' where A is alpha and N is numeric.

Thanks in advance

Since you are saying this one has you stumped .. I am assuming that you cant use cut and have looked at sed as follows.

sed -e 's/[a-z]*//;s///g' filename> NumericFile
sed -e 's/[0-9]*//;s///g filename> AlphaFile

sorry too early in the morning and too long staring at the screen

replace sed as follows
sed -e 's/[a-z]*//g' and sed -e 's/[0-9]*//g' you dont need all the extras.

I am sorry I did not make this clear. I need to split the date into those lines that match NNAAAA, and those that do not. For example:

Sample data:
aa1234
bb9876
root
nobody

Would produce one file or variable containing root and nobody, and another containing aa1234 and bb9876

Code:
if [[ $something == [a-zA-Z][a-zA-Z][0-9][0-9][0-9][0-9] ]]; then
        echo one file
else
        echo the other file
fi

Try...
Code:
var1=$(grep '[a-zA-Z][a-zA-Z][0-9][0-9][0-9][0-9]' file1)
var2=$(grep -v '[a-zA-Z][a-zA-Z][0-9][0-9][0-9][0-9]' file1)
