I need to be able to convert HTML email messages saved as text files (.eml or .msg) to PDF documents, one PDF per email, retaining formatting and images.
Are there any Linux tools that will allow me to do this from the command line (so it can be scripted)?

As much as I didn't want to ask a sed question, especially considering there's already one on this page I've looked as best I could and cant find the solution. Id like to use sed to replace occurrences of a pattern but exclude two or 3 specific lines that are not consecutive. For example I know with 1,10 i could exclude the first 10 lines, what is the syntax if I just wanted to exclude line 3 and 7. The sed command I'm working with right now is for rearranging Ethernets.
cat /etc/udev/rules.d/70-persistent-net.rules | sed -e '/'"$found1fullmac"'/!s/eth1/'"found1eth"'/' > /etc/udev/rules.d/70-persistent-net.rules
I would like to replace $found1fullmac with two variables representing line numbers to exclude from the replacement.

I want to insert the text "DB dept" in the last line of passwd file which looks like this right now
Quote:
newuser:x:717:717::/home/sacharje:/bin/bash
And I want it to be like this:
Quote:
newuser:x:717:717: DB dept:/home/sacharje:/bin/bash
I tried to do that with sed but failed, I'd like to know the proper syntex with sed to achieve this.

I have an SQL dump, file.sql that has many references to a particular domain, d1.com. I would like to run a command that can replace every occurrence of d1.com with d2.com. I've tried looking into sed before but the man pages are quite daunting.

I am not especially cli adept so could someone tell me the best way to use the diff command to get the difference between a string of text and the contents of a file instead of between the contents of two files?

I don't understand why this is so difficult.In the old days, there was lpforms which allowed some formatting. CUPS did not see fit to implement this into it's lp package.cgi-...-cgi?lpforms+1In the old days, lpr allowed you to select a font in the command line with -1=fontname. CUPS did not see fit to implement this into it's lpr package.htmIn the old days, printers had fonts installed on them that you could access. Modern printers don't seem to have this. So now I still need to be able to select a font when I print certain text files from the command line but it seems this is impossible. I've been working with instances and lpoptions, which allows me to do a lot of other things I need like orientation and margins and even set the font size, but I still cannot choose a font other than the default.

I want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.

Been at this all morning and fail on every attempt.
I have a file called sitemapindex.xml
Its contents just are names of the other sitemaps. Google gets pissy because it isn't in a http:// format.
So, I need "<loc>sitemap-c1mediawiki-............</loc>" to be replaced with "<loc>http://domain.tld/sitemap-c1mediawiki-............</loc>".
Here's the expression I've been trying:
find /path/to/site/sitemap-index-c1mediawiki* -type f | xargs sed -i 's/[<loc>sitemap]/[<loc>http://domain.tld/]/'
It fails.
I've tried with and without brackets.

After several searches and a bit of messing around, it's clear I'm missing something, so was wondering if anyone could offer any insight?

How could I replace text in one file with text from another file using sed?
The text in each of the files would be surrounded by a starting and ending delimiter or a starting tag, say like /* */ so to easily find them.

This should be simple but I can't seem to find what I am looking for.I want to search a text file for the existence of certain strings and execute a command if they exist, something along the lines of:
if <string> exists
command
or
if <any member of this list exists>
command
I know how to manually search a file with grep, cat, etc., but the "if this exists" part eludes me.

im trying to output a list of running processes via a shell script. At the moment i got this which outputs the processes to a text file called out.
echo $(ps aux) >>out
The problem is though, the processes are all just one big block of text which makes it hard to read. Does anyone know how to sort the output to a text file so that it prints to the text file at 1 process per line? I know its probably simple but im very new to linux.
