Ed,
It did work. Thank you.
But I didn`t understand acctually what you did.
In the first line, you look for the @[EMAIL PROTECTED]
sign in the begining of of the
line, then you print what you search. OK, then a=!a and b=1, I didn`t
understand what does this means.
/^@[EMAIL PROTECTED]
{ print; a=!a; b=1; next }
a || /^!/ { print; next }
b { print $1,$2,"-"$3 }
What can I read to understand it better?
Thank you again.
If I need to to that, with many files? Could I do it with awk? Or will
I need to use some shell scripting?
$
for file in *.dat; do ./trans.sh $file > $file.new; done
transf.sh
#!/bin/sh
awk ' /^@[EMAIL PROTECTED]
{ print; a=!a; b=1; next }
a || /^!/ { print; next }
b { print $1,$2,"-"$3 }' $1
Any suggestions?
