[gnutls-devel] GnuTLS | mech-list.h: generate unique entries (6099715e)

[Development of GNU's TLS library]

Dmitry Eremin-Solenikov started a new discussion on src/gen-mech-list.sh:

>  # Exclude duplicate and uninteresting entries
>  EXCLUDED="(CKM_VENDOR_DEFINED\s|CKM_CAST128_MAC\s|CKM_CAST128_KEY_GEN\s|CKM_CAST128_ECB\s|CKM_CAST128_CBC\s|CKM_CAST128_MAC_GENERAL\s|CKM_CAST128_CBC_PAD\s|CKM_PBE_MD5_CAST128_CBC\s|CKM_PBE_SHA1_CAST128_CBC\s|CKM_EC_KEY_PAIR_GEN\s)"

Why do you need to split these pipelines instead of just `cat ${HEADER} | grep -E "..." | grep -vE "..." | awk '{...}' | sort | uniq`? Or even `... | sort -u`?
