Hi.
Thanks to ZB for pointing out the part I apparently skipped over. If that is desired, then the
sed becomes slightly more complex (or mysterious), and it is easier to build it into a separate
sed script file:
% cat s3
Code:
#!/bin/sh
# @(#) s3 Demonstrate sed line split and merge.
set -o nounset
echo " sh version: $BASH_VERSION" >&2
sed --version | head -1
FILE=${1-data1}
echo
echo " Input file:"
nl $FILE
cat >script <<'EOF'
/==Document$/{
N
s/==Document\n/==\nDocument/
}
EOF
echo
echo " Output"
sed -f script $FILE |
nl
exit 0
producing:
Code:
% ./s3
sh version: 2.05b.0(1)-release
GNU sed version 4.1.2
Input file:
1 Beginning.
2 This is a test set of data.
3 ==============
4 this is ok.
5 ==============
6 this is ok, too.
7 =============Document
8 this we want changed.
9 =============
10 this is ok again.
11 End
Output
1 Beginning.

5 ==============
