Word wrap with sed
Hi,

I got some timetable in a file but it is all mixed up like this

01:00 hgrtwhrt #104:00 tyergethr05:00
tqqrthd qrth #107:00 qhtrhqerth10:00 qerthrthqr qtrqthr
qthrrt11:00 thqrthqrthrr
rthgreth #212:00 trhrthrth14:00 wrthwrtwrqrthwrthwr
#2116:00 trqhthtr: rthrthr17:00 rtwhtrhwrth rthwrt ghrthrw #119:00
rwhrt rwthwrtr #322:00 wrthrwth wrhrths23:00 wtrhwr
twrthrthwrt #1

Is it possible to insert a word wrap?
I'd like to get a list like this

01:00 hgrtwhrt #1
04:00 tyergethr
05:00 tqqrthd qrth #1
07:00 qhtrhqerth
10:00 qerthrthqr qtrqthr

I thought about a word wrap 2 characters before each colon?
Thanks for your help

Code:
echo $(cat file1) | sed -e "s/\([0-9][0-9]:\)/@\1/g" | awk -v RS="@" '1'

01:00 hgrtwhrt #1
04:00 tyergethr
05:00 tqqrthd qrth #1
07:00 qhtrhqerth
10:00 qerthrthqr qtrqthr qthrrt

Try the following awk command :
Code:
awk '{gsub(/..:/, "\n&"); print}' inputfile

My previous solution doesn't manage the splitted record.
A new solution :
Code:
awk -v RS="" '{ gsub(/\n/, " ");gsub(/[0-9][0-9]:/, "\n&");print}' file1.dat

Just a little problem, there is an empty record generated at the begining of the result.

the easiest way is just to use sed only without awk as below (code will be more fast):-
kindly note that there is a new line in the two line code below so kindly write it as it is literally:


Code:
cat inpu_file | xargs | sed -e 's/\([0-9][0-9]:\)/\
\1/g'



output:-

Code:
01:00 hgrtwhrt #1
04:00 tyergethr
05:00 tqqrthd qrth #1
07:00 qhtrhqerth
10:00 qerthrthqr qtrqthr qthrrt
11:00 thqrthqrthrr rthgreth #2
12:00 trhrthrth
14:00 wrthwrtwrqrthwrthwr #21
16:00 trqhthtr: rthrthr
17:00 rtwhtrhwrth rthwrt ghrthrw #1
19:00 rwhrt rwthwrtr #3
22:00 wrthrwth wrhrths
23:00 wtrhwr twrthrthwrt #1

change the whole file into one line.

Code:
echo $(cat file1)
cat inpu_file | xargs
xargs < urfile
awk -v RS="" 'gsub(/\n/, " ")1'  
tr -d '\n' < urfile
awk '{printf $0}' urfile
