General :: Replacing The Text In Same File Using SED Command?
Oct 11, 2010
I have a String like "A.words=Ajay,Anil" in file A.And it contains a lot of other information also. I wanted to replace "Ajay,Anil" with "Vijay,Vinay" with sed command with using existing file only(not using another file)
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 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.
First I hope to undrestand my English word because Iam Arabic girl and not so good in English...
my problem is:
I wrote code in .c file and I run that code on the prompt command, its ture but I want after the out put copy the code on the command by some statment in the code , how can I do that?
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 used a script that renamed my file eg 'echo webutil.olb | tr [A-Z] [a-z]' i wanted to rename it back to webutil.olb. How do i do this for many other files that i have
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.
I've been reading tutorials of Linux sed command, but haven't got anything yet. the problem is : I want to insert a line into my DNS database file which has a pattern like below:
<Domain name> 3tabs here <IN> <A> <ip address>
the question is : how to add a line into a file like this using linux sed command? I have problem inserting tabs and the spaces!
I'm gonna replace my machine's ip address and hostname using awk command. the pattern of the file is like the following...ip address="192.168.1.100"the script must ask the ip address from the user and replace it with the ip address in the quotation.
I'm having problems with Tomboy. I have a few hundred note files and I need to go through all of them and replace all instances of "<link:broken>a</link:broken>" with "a". Is there a bash command I can use to do this?
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.
