thanks.

>I assume you want to remove all the empty lines in the files.

no!

I want in general,to use multiple sed commands,not just to delete empty lines.

hello!
I have a few sed commands
sed '/^$/d' < $1 > tmp.t
sed '/^ \{3,\}/d' < tmp.t > tmp1.txt
.....
how can I write them in a single line?

sed '/^$/d' < $1 > | '/^ \{3,\}/d' < $1 > tmp1.txt...

yes,I know...$0 and change substr(...,...,...)....

but is ok ;)

000000382019-0001-01john stewart 056628826 //..more fields
000000589219-0000-21joe warren //...more fields

should be :

0000003820,19-0001-01,john stewart ...

<what I meant there is that if the no. of characters excluding spaces is constant


including spaces is constant :)

I get some strage results!

awk -v LIN="${0}" '{print substr(LIN,1,6)","substr(LIN,7,5)" ,"substr(LIN,13,4)","substr(LIN,17,3)
" ,"substr(LIN,21,4)}' < file.txt > result.txt


why?

thanks!!!
it rocks ;)

how I will use it like this:
instead of
echo |awk -v LIN="${LINE}"
to use plain $0
'{print substr($0,1,6)","substr($0,7,5)" ,"...

I guess the problem will be with...

fields in a record which is lets say 30 chars another is 40 may contain spaces...

it doesn't solve the problem...

in each file I have to change
substr parameters
instead of substr($1,7,11)" ,"substr($2,1,4)","substr($2,5,7)"

I want...

thanks a lot!

is there a more generic way to do it?
instead of $1/$2....to parse the whole line?
becouse like this I will have to change the script each time I use it for another file.

thanks...

hello!

I have a file with fixed record length...

format:

123445asdfg 4343777 sfgg

I wanna convert it to

123445,asdfg ,4343,777 ,sfgg

is there any way to do it?

sed/grep/awk??
