Editing HTML with FTP access

Shell Programming and Scripting

Hello, I've got a similar problem. I want to add some lines before the ending of the <head> tags. How can I do that?
Example.

<head>
 <some website stuff here>
 <My stuff>
<head>

I'd like to do that automatically with ftp. Is it possible to activate a sort of syncing in order to update changed files? And I'd also like to prevent adding <my stuff> in files that already have <my stuff> .
Thank you!

Please post your question in another thread.

FTP is very simple and stupid. It can't edit files. You could download them, edit them, and upload them back.

Yes, I know that ftp is stupid and it can't edit files. I was looking for a sort of ftp syncing solution for modified files, a bit like dropbox. But my main question was, and remains: I want to add some lines before the ending of the <head> tags. How can I do that?
Example. HTML Code:

<head>
<some website stuff here>
 <My stuff>
<head>

I'd also like to prevent adding <my stuff> in files that already have <my stuff> .

Thank you.

Please use code tags for code,

```text

Hmmm. Keep a line like <!-- MY HEADER --> in your stuff so you can scan for it to tell if it's there. <!-- END MY HEADER --> would also be good in case you need to remove it later.

OLDIFS="$IFS"
IFS="/"

N=0

find /path/to/files -type f | while read FILEPATH
do
        set -- $FILEPATH # $1=path, $2=to, $3=files, $3=subdir, etc
        shift 3 # Discard 'path', 'to', 'files'
        DESTDIR="/home/username/public_html/"$* # /home/username/public_html/subdir/filename

        grep "<!-- MY HEADER -->" "$FILEPATH" && continue
        if [ ! -e "$NEWPATH" ] || [ "$FILEPATH" -nt "$NEWPATH" ]
        then
                awk -f newheader.awk header="/path/to/headerfile" "$FILEPATH" > "/tmp/$$-$N"
                echo "put \"/tmp/$$-$N\" \"$NEWPATH\""                
                let N=N+1
        fi
done > list-of-files-to-upload

ftp <<EOF
...

`cat list-of-files-to-upload`
...
EOF

rm -f /tmp/$$-*

I cannot guarantee that newhead.awk is bulletproof. Parsing XML is not trivial.

$ cat newhead.awk

BEGIN {
        FS=">"
        OFS=">"
        RS="<"
        ORS="<"
}

NR==1 { next } # The first "line" is blank when RS=<

/^[!?]/ { printf("%s", RS $0 ); next    }   # print XML specification junk

# Handle open-tags
match($0, /^[^\/ \r\n\t>]+/) {
        TAG=substr(toupper($0), RSTART, RLENGTH);
        TAGS=TAG "%" TAGS;
}

# Handle close-tags
/^[\/]/ {
        sub(/^\//, "", $1);
        sub("^.*" toupper($1) "%", "", TAGS);
        $1="/"$1
}

{       printf("<%s", $0);      } # Print everything

# Add extra stuff to HEAD section
TAGS ~ /^HEAD%/ {
        P=""
        printf("\n");
        while((getline < headerfile) > 0)
        {
                printf("%s%s", P, $0);
                P=RS;
        }
        printf("\n");
}
