Splitting large text file on every blank line

Question

I\'m having a bit trouble of splitting a large text file into multiple smaller ones. Syntax of my text file is the following:

Answer 1

You could use the csplit command:

csplit \
    --quiet \
    --prefix=whatever \
    --suffix-format=%02d.txt \
    --suppress-matched \
    infile.txt /^$/ {*}

POSIX csplit only uses short options and doesn't know --suffix and --suppress-matched, so this requires GNU csplit.

This is what the options do:

• --quiet – suppress output of file sizes
• --prefix=whatever – use whatever instead fo the default xx filename prefix
• --suffix-format=%02d.txt – append .txt to the default two digit suffix
• --suppress-matched – don't include the lines matching the pattern on which the input is split
• /^$/ {*} – split on pattern "empty line" (/^$/) as often as possible ({*})
