[opensuse] OT: Need program to replace text
I have a bunch of html files that i need to do a couple of things to: 1.remove the html and head tags and replace them with other code 2.rename the file to .php Isn't there a program that will search all the files in a given directory for html and head and then replace that with something else? Then rename the files? I have seen the replace function in gedit but it does not accept the php code that needs to be inserted (i think the code is to long). Anyone no of a program/way that will accomplish this? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I have a long replacement text like this: <?php require('../../wp-blog-header.php'); ?><?php get_header(); ?><?php include(TEMPLATEPATH."/sidebar1.php");?><div id="main"><div id="content">
and the text that needs to be replaced is: <HTML><HEAD><TITLE>Net Bible - Genesis </TITLE><LINK REL=Stylesheet HREF="style.css" TYPE="text/css" MEDIA=screen></HEAD><body><p class=title>
So the command i run looks like this; sed -i 's/<HTML><HEAD><TITLE>Net Bible - Genesis </TITLE><LINK REL=Stylesheet HREF="style.css" TYPE="text/css" MEDIA=screen></HEAD><body><p class=title>/<?php require('../../wp-blog-header.php'); ?><?php get_header(); ?><?php include(TEMPLATEPATH."/sidebar1.php");?><div id="main"><div id="content">/g' ./*
and i get this error: sed: -e expression #1, char 99: unknown option to `s'
I guess you've to escape various symbols first ;) Greetings Michael

There are a couple of reasons why this does not work. First and foremost: since your replacement text contains '/', you should use a text separator different from '/' like s#foo#bar#g If I remember correctly < and > are also special (have to look that up) and you should escape them: \< and \>. Finally, this would only work on a consecutive text without newlines and I think that is not what you have in mind. Look up the c command in sed, because I think that is what you need. This lets you replace a couple of lines with a couple of other lines. -- Jos van Kan registered Linux user #152704 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

No. They're special to the shell, but since you'll surely quote the entire sed argument holding the editing command, that's not an issue. In fact, putting backslash before angle brackets gives them special meaning, namely word boundaries, left and right, for \< and \>, resp.

There's a difference between command and option. You use the -ic option (I don't know what that does, but obviously not what you want) and the s command. I suggest you do a read up on sed.

No, but you can write a shell-script using the find command and use the -exec option
Then rename the files?
Do you mean the mv command?

Cannot help you with the first requirement but regarding renaming the files use XnView to do this. XnView is basically a picture viewing application but, surprisingly, it doesn't care what the files are when you use its Batch Rename facility - it will happily rename the extension of the files for you. Place all the html-extension files in the one directory then use the Batch Rename facility in XnView to rename the extenions to .php.

No problems with the command line but after making a file called "rename" with the above code in it (rename file is located in the directory where i need to rename the files), i run ./rename and instead of the files being renamed they are just copied. So, 1file.htm has become 1file.htmc and every time i run rename it just adds a "c" to the end of the file name.

I did some experimenting, and admittedly there are some caveats with that stuff. But here is a skeleton for you: perl -p -i -0777 \ -e 's/^.*<!DOCTYPE\s+html.*<body>/PHP-Header\n/si;' \ -e 's:</body>.*$:<?PHP-Footer?>\n:si;' \ -e 's:moreoldstuff:newoldstuff:g;' \ *.html Note: This is one single line of shell command. I just reformatted it for better legibility. Let's take this apart. perl -p : This reads the files specified on the command line as input files line by line and prints each single line. If you don't do anything else, this is a glorified "copy" command. But with regular search-and-replace, this becomes more like a "sed" call. Note there is also "perl -n" which does not print; you'd have to append 'p' ("print") to each regexp replace to write something to the output file, or use the regular perl "print" command. -i : This does all changes in-place, i.e. you don't need to supply an input and an output file. Otherwise you'd have to write your own loop in the shell and do something like perl -p -e'<do something>' <infile >outfile perl -i does that loop for you, reads from each infile from the command line, writes to a new file and renames the new file afterwards to the name of the infile. You can also specify a backup file extension: "perl -i.bak" will back up all old infiles to "infile.bak". -e : This specifies one perl expression. You can use several -e args, but then you need to delimit all (except the last one) with a semicolon. A bit unlike "sed", unfortunately. By default, perl reads one single line from the infile, processes it with all your -e expressions and (with -p) writes it to the outfile. This is what most people need in most cases. You can use that as a "sed" substitute with in-place editing - this is what I wrote in my first post to this thread: perl -p -i -e 's/oldstuff/newstuff/g' The '/g' at the end tells perl to do that globally, i.e., more than once. Otherwise it would just replace one single time. Just like "sed". In your special case, though, you want to search and replace over multiple lines. That's a bit tricker. For one thing, you need to tell perl to read more than just one line at a time. For example, the entire file at once. This is what -0777 does: It changes the input record delimiter from \n (newline) to character 0777 (octal) which doesn't exist, thus the entire file is read at once. (See "man perlrun"). Then, you also have to make perl match more than just one single line in a regular expression: s/oldstuff/morestuff/s Note that this is necessary in addition to having the whole file in one single string. I also added /i to match case-insensitive which makes sense for HTML tags. Quoting regular expressions is another tricky part. You have to watch carefully which characters in "oldstuff" have a special meaning in perl's (very powerful!) regular expressions. But typically that's not a problem because that part is hand-written, not variable stuff coming from a file. \s is useful: It's a shorthand for "any kind of whitespace character" - blank, tab, newline. "\s+" means "at least one whitespace character, but maybe more (any number)". In the replace text there are a lot less characters with special meaning. $1, $2, ... $9 come to mind; they are placeholders for an expression in parentheses in "oldstuff". If your search regexp contains slashes, it makes sense to use some other delimiter character; this is what I did in the other -e expressions: s:oldstuff/with/slashes:newstuff: You could also escape every single slash with a backslash, but that's tedious, error-prone and it looks ugly: s:oldstuff\/with\/slashes/newstuff/ Did I forget something? Probably. But hey, I don't want to deprive you of all intellectual challenges. ;-) I hope I gave you some good starting points, though.
