Simple IPv4 parser written in Nim with gzip files handling and build compatibility for musl
Parse IPv4 address occurances
+ support for reading *.gz files
+ PATTERN support regex syntax
+ Regex for IPv4 is fast and simple: \b[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\b
WARNING: This Regex can obviously parse some non IPv4 addresses
+ Reading STDIN if "-" (dash) specified
USAGE:
parseip [options] [--] [<FILE>]...
parseip [options] [-]
OPTIONS:
-c --clean Cleaner output, do not print address counts
+ Output is sorted
+ Honor --limit settings
-e --exclude=PATTERN Exclude IP if line contains PATTERN
+ usable with -p, exclude has priority
-h --help Show this help
-i --ignorecase Ignore case for -p and -e options
-l --limit=NUM Limit output number of addresses [default: 25]
+ For no limit set to 0
-r --remove=NUM Uniq IPs after removing NUM of octets from IP
+ NUM can be number in range: 1-3
-p --parse=PATTERN Parse IP only if line contains PATTERN
+ usable with -e, exclude has priority
-n --nosort Do not sort output (performance gain is almost zero)
+ Sorting is by occurances of IPs
-s --seek=BYTES Skip BYTES when reading input
+ [K,M,G] standard unit suffixes can be used
+ Unit base is 1024
-V --version Version of program
-v --verbose Show what is going on
EXAMPLES:
cat FILE |parseip -
parseip --clean /var/log/syslog
parseip --limit 10 FILE.gz
parseip --parse "123.123.123.1|123.123.123.2" FILE
parseip --ignorecase --parse "sasl" --exclude "127.0.0.1|127.0.0.2" /var/log/maillog
parseip --parse "127.0.0.[0-9]+" FILE
parseip --seek 20M /var/log/messages
parseip --clean --remove 1 FILE
