I tab delimited a vcf file so that I could filter on the 'type' information, which was included in a series of information separated by semicolons. I now want to filter for lines that contain 'TYPE=snp'. Some of the types includes 'TYPE=snp, del', or another combination of types of variants. I want all lines that include snp in it, including the ones with other types. How can I filter in this way? I have only figured out how to filter for the exact expression of 'TYPE=snp'.
