Sed question 1

[paleogryph]

RH8 Linux using bash.

Is it possible to sed a line so that it "Shift-j"'s the end of the line?

sed 's/$/shift-j/' or something like that.

In other words, with vi I could "shift-j" a line and pull the line below up and add it to the current line. I'm greping lines containing BLOCK, but I need to also grab the 3 lines below and concatenate them all into one line.

Is this possible?

paste -s will join lines, but you could use awk to search for BLOCK and join the subsequent lines. Not tested...

awk '/BLOCK/ {for(x=0;x<3;x++){printf $0 &quot; &quot;;getline}; print $0}' $FILE

Ygor you rock!
Works great.

Although solved well, you can still use sed. Such as appending the empty hold space to the pattern space. E.g.

sed 'G' $FILE
