New Line charactre in sed

[Alex Galitsky]

Good day

I have a file with no New Lines characters, and would like to put New Line before certain pattern
Say, it looks like aa111bbccdd111eeerr111ttt
and 111 is indicator where new line should start

I tried to use command:


sed -e "s/111/`echo \\\t`111/g" NewFile
but it did not work :-(

Can you help me, please?

try:

sed 's/[pattern]/\n[pattern]/g'

sorry that won't work - don't know what I was thinking - hang on I'm looking.

Hi Alex,
This will works

#echo "000111jkiejrn" > test

#sed 's/111/111X/g' test | tr "111X" "111\012]"
and result is what you want.
000111
jkiejrn

Not elegant but it works .. (2 steps needed..), assuming the file "test" has that line ..

# cat test|sed 's/111/:111/g'|tr ":" '\012'

[harry d brown jr]

something like this:

#!/usr/bin/ksh
echo "aa111bbccdd111eeerr111ttt" |
awk '{X = split($0,A,/111/);
for (i=1; i {printf("%s\n",A[i]);}
}'

Hi Alex,

I am not a sed expert but I tried :-)

hostAprompt>cat testfile
aa111bbccdd111eeerr111ttt

hostAprompt>sed 's/111/&new/' testfile | tr "new" "\n"
aa111
ewbbccdd111eeerr111ttt

close huh ?

Oh yeah !

Do it globally ...(add g at the end)

sed 's/111/&new/g' testfile | tr "new" "\n"

Hi Alex,

See my attached script. The sed command is split on 2 lines. The "\" at the end of the first line escapes the newline that terminates the line. Basically, it is simply continuing the command line on the next line.

It is important that there are no spaces before or after the "\".

Alex,

Here is a variation on Harry's awk statement.

echo "aa111bbccdd111eeerr111ttt" |
awk -F"111" '{ for ( i = 0 ; i <= NF ; i++ )
print $i }'

This produces the following output:

aa
bbccdd
eeerr
ttt

l1:/tmp 107 > glob "aa111bbccdd111eeerr111ttt" > xx
l1:/tmp 108 > perl -lne 'BEGIN{$/="111"}print$_,$/' xx
aa111
bbccdd111
eeerr111
ttt111
l1:/tmp 109 >

To All:
thank you very much for your replays. I learned a lot :-)
I used Darrell Allen's approach - specail thanks to Darrell - but other's programs are also great!

Thank you again,

Alex
