I have a text file with a marker somewhere in the middle:
one
two
three
blah-blah *MARKER* blah-blah
four
five
six
...
I just need to split this file in two files, first containing everything before MARKER, and second one containing everything after MARKER. It seems it can be done in one line with awk or sed, I just can't figure out how.
I tried the easy way — using csplit
, but csplit doesn't play well with Unicode text.
Read a file (data stream, variable) line-by-line (and/or field-by-field)? We can use sed with w option to split a file into mutiple files. Files can be split by specifying line address or pattern.
To split a file into pieces, you simply use the split command. By default, the split command uses a very simple naming scheme. The file chunks will be named xaa, xab, xac, etc., and, presumably, if you break up a file that is sufficiently large, you might even get chunks named xza and xzz.
you can do it easily with awk
awk -vRS="MARKER" '{print $0>NR".txt"}' file
Try this:
awk '/MARKER/{n++}{print >"out" n ".txt" }' final.txt
It will read input from final.txt and produces out1.txt, out2.txt, etc...
sed -n '/MARKER/q;p' inputfile > outputfile1
sed -n '/MARKER/{:a;n;p;ba}' inputfile > outputfile2
Or all in one:
sed -n -e '/MARKER/! w outputfile1' -e'/MARKER/{:a;n;w outputfile2' -e 'ba}' inputfile
The split
command will almost do what you want:
$ split -p '\*MARKER\*' splitee
$ cat xaa
one
two
three
$ cat xab
blah-blah *MARKER* blah-blah
four
five
six
$ tail -n+2 xab
four
five
six
Perhaps it's close enough for your needs.
I have no idea if it does any better with Unicode than csplit, though.
