Programming :: Bash Search Line And Replace Hex To Binary?
Jul 7, 2011I need a command to search a string in a file and then to convert the next string in the same line from hexadecimal to binary. I was able to put everything in capitals. The original file can be as such:
E 2
C 1 794
T ffff
E 2

It is not always FFFF! I am trying to do this in a file at once, not reading line by line (using while).

Apr 7, 2009I'm fairly comfortable with emacs but I can't seem to find how to do this. I deal with a lot of text files and find myself performing a lot of regular expression replacements to correct the formatting of the text -- or to extract certain tidbits of data from large ugly-looking files.
I know how to perform a regular expression replacement in one buffer at a time. But how do you perform a regular expression search and replace across all open buffers? I have found a method to perform a regex search and replace across a directory by marking files but I need to do it in the open buffers.
Ubuntu :: Multiple Search And Replace In Documents - Creating A Sed Script?
Jul 16, 2011I want to do search and replace in multiple files. I've seen that it possible to create a sed script but I haven't got the talent to do it myselfWhatd is to locate all instances of a word - lets say 'day' - and replace it with for example 'night' in all odm-documents in a specific folder. It would be great if the search only matched whole words and was case sensitive.

Aug 26, 2009Below is extract of my file:
What I need is to replace "--destination-path=" with "--destination-path=/home/dest"
i.e. desired output is ----destination-path=/home/dest
I could achieve it with below command
$cat outgoing-xfer|grep destination-path|perl -pi -e "s/destination-path=/destination-path=/home/dest/g"
But the problem is that in this case i just wanted to append "/home/dest" for which I could easily escape "/" with just two "", but I wonder if i have a long path like "/a/b/c/d/e/f/g/h/i/j" I will have to escape so many /. Is there any other way by which I can avoid escaping forward slash.
I tried following:
But receiving follo error
Bareword found where operator expected at -e line 1, near "s/destination-path=/'destination-path=/home"
syntax error at -e line 1, near "s/destination-path=/'destination-path=/home"
Bad name after dest' at -e line 1. tried with enclosing in double quotes as well but in vain
Programming :: Using Sed To Search And Replace Backwards?
Oct 25, 2010I'm trying to use sed to search and replace backwards. The problem is that I have a shell script that is required to put commas into big numbers. For example
9999999 as 9,999,999
I've tried a few things, but none seem to work:
Code:
$ echo 9999999 | sed -e 's/([0-9]{3})/,1/g'
,999,9999
$ echo 9999999 | sed -e 's/([0-9]{3})$/1,/g' -e 's/([0-9]{3})/1,/g'
999,999,9,
$ echo 9999999 | sed -e 's/([0-9]{3})$/1,/g' -e 's/([0-9]{3})/,1/g'
[ode]....
It would be much easier if I could search backwards! For example Bash parameter substitution style:
Code:
$ echo 9999999 | sed -e 's%([0-9]{3})%,1%g'
General :: Replace Multiple Instances From X To Y In Line
Feb 1, 2010I have a line of text with multiple web links in the line. I'd like to replace the actual links with the text "<web-link>" so I don't accidentally hit them while reading on my iphone. I've tried many versions of the following sed command, sed 's/(http.*)/<web_link>/g', but it simply replaces everything between the first instance of "(http" and the last instance of ")" with <web_link>, or does nothing at all.
Ex: This line has a link to a web page (http://www.webpage.com/file.html) then some more text (extra text) and then another link (http://www.nextwebpage.com.index.html) to a website.
$ echo "This line has a link to a web page (http://www.webpage.com/file.html) then some more text (extra text) and then another link (http://www.nextwebpage.com.index.html) to a website." | sed 's/(http.*)/<web_link>/g'
What I get is: This line has a link to a web page <web_link> to a website.
What I'd like is: This line has a link to a web page <web_link> then some more text (extra text) and then another link <web_link> to a website.
What am I doing wrong with my sed command?

Ubuntu :: Command Line - Find And Replace Text Within Multiple Files?
Aug 28, 2010I'm pretty sure this is doable from the command line, but my CLI skills have degraded a lot since my pre-Y2K admin days. The goal is to search all the files in the directory for a very long string of text and replace it with another string of text. The text being searched for is my Google Adsense code (which will be stripped from my website) and it will be replaced with a placeholder so I can easily tack something else in there in the future.
Seeing how I have that long snip of code on about 100 pages, automating the process would make life easier.
If I was searching for a single word, I can see ways to do this.
If I paste the code I'm searching for into a text file, is there a way to:
find (contents of oldstring.txt) and replace with (contents of newstring.txt)?

Programming :: Replace Html In Multiple Files (80+)

All of the examples I've found don't see to work with all of the special characters in the line that I need to replace. Then I need to add a line after the above edit like this: types = [ "device-mapper", 253 ]
Programming :: Multi-line Find - Replace With GnuWin32 Sed?
Apr 26, 2009I would like to have a script that will do a search in an XML file for a specific block of XML code and replace it with a different block of XML code using the Windows build of GNU Sed 4.1.5.
Here's the text I want to find:
Code:
And here's what I want to replace it with:
Code:
There is however a lot of stuff in there that would mess up sed, and the one example from the sed FAQ (from the Sourceforge site) that looked promising and easy enough to figure out (4.23.3. Try to use a block of "literal strings") fails with this error message: sed: file blockrep.sed line 18: unterminated `s' command
Anyone got any ideas, or even an alternate program that can do this? (Preferably one that I can automate.)
Programming :: S/ Command Won't Replace Two Occurrences Of Pattern On Same Line
Dec 15, 2009Here's the actual line of code, which exists in a bash script:
Code:
I want to replace instances like this:
Code:
with this:
Code:
Using this:
Code:
Which works great when there's only ONE of the pattern on the line. But in a case like the "actual line" I posted first, where there are two patterns, separated by a slash, only ONE gets replaced
Watch:
Code:
Why? There must be (among many other things) something I'm not knowing about sed, that's causing this.
-- I'm currently using the ~ (tilde) as the separator in the sed command. It doesn't matter, I've used / ~ and % with no difference.
-- As a test, I tried putting a different character(s) in the middle of the original pattern instead of the / but that made no difference.
-- I've come up with various similar but slightly different regexs that will do this replacement, but they all have had this same result.
-- I tried the sed single-quoted, double-quoted, and unquoted; the latter fails to execute, and the formers both work as described here: wrong.
Programming :: Replace Character With Hex Value Choosing From Shell Cmd Line?
Jun 9, 2011I am bouncing a file across platforms (windows->solaris->mainframe), and the file is starting out with a "special" character (the registered trademark "circle R") in some of the records. This character is not in the EBCDIC character set on the MF, so it is unrecognizable. The MF developer I am working with asked if it is possible to replace the character with a specific hex value (AF) before it gets to the MF.
I was putzing around with sed, tr, etc. on the ksh command line, hoping to find an easy way to get one of them to substitute hex instead of ASCII. I have found that the usual shell utilities recognize the trademark character, so homing in on what to replace is solved. But I cannot get anything to actually substitute in the hex sequence I want. E.g. I was thinking something like...
>cat special_file | sed 's/R/AF/g'
But my version of sed does not seem to have hex "editing" capability.
