Top Forums Shell Programming and Scripting sed failing with multiline html loaded with metacharacters Post 302908120 by MadeInGermany on Thursday 3rd of July 2014 05:51:38 PM

Say you your file is file.html.
Save the old (to be replaced) text in the file old.
Save your new (replacement) text in the file new.
Then run
Code:
diff -c old new | patch file.html

It will apply the differences directly to file.html.

If you want to modify multiple files this way, you need a loop:
Code:
for file in file1.html file2.html
do
  diff -c old new | patch "$file"
done

NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files SYNOPSIS
xzcmp [cmp_options] file1 [file2] xzdiff [diff_options] file1 [file2] lzcmp [cmp_options] file1 [file2] lzdiff [diff_options] file1 [file2] DESCRIPTION
xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1). All options specified are passed directly to cmp(1) or diff(1). If only one file is specified, then the files compared are file1 (which must have a suffix of a supported compression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncompressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp(1) or diff(1) is preserved. The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils. SEE ALSO
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1) BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified. Tukaani 2011-03-19 XZDIFF(1)
