Using sed, I am trying to append four commas ',,,,' at the end of lines containing the pattern 'Response' in a text file with lines such as these:

I want to create some files of a specific size containing a repeating pattern. I did some research and found that I can create a file and fill it with (fairly) random data by using dd like so: dd if=/dev/urandom of=myfile.dat bs=$(( 1024 * 1024 )) count=100 (Creates a 100 MB file.) I found that here: Quickly creating large files.
Rather than fill a file with random data, I'd like to use these patterns: 0xaa, 0x55, 0xff, and 0x00 (one per file). Is there a simple way to accomplish this?
I have two files list1.cfg and list2.cfg both files contains differentrecords details like
List1.cfg
NAME1:25:C:NAME LINE1:
NAME2:25:C:NAME LINE2:
CITY:25:C:City:
[code]....
Now I want to append contents list2.cfg to list1.cfg(It ispposible using cat list2.cfg >>list1.cfg) but I want to check if content of (record) in list2.cfg is present in list1.cfg then dont append it otherwise append it.
To put it simply I want the egrep command to return matches for a group rather than the whole pattern itself.For example:
Code:
egrep "reals([0-9]+?m[0-9]+?.[0-9]{3}s)" tmp
returns
"real 0m1.001s"
But I want it to return just "0m1.001s", the portion is the group. I can just apply egrep to whatever the first command returns but is there an easier way to do it?
I am trying to create a shell script, on taking a input file as parameter, which need to do 3 things
1) create a copy of existing file.
2) add a new line to the copied file.
3) strip off all the absolute paths inside the copied file
The first 2 points are straight forward. but i am finding it difficult to acheive the 3rd point. myself not very good with awk and sed. but gave it a shot in vain. For example, the input script consists of below,
PROGRAM=`/usr/bin/basename $0`
HOST=`/usr/bin/uname -n`
echo Start $PROGRAM `/usr/bin/date` |
/usr/bin/tee -a $LOG
The output of the script should look like,
PROGRAM=`basename $0`
HOST=`uname -n`
echo Start $PROGRAM `date` |
tee -a $LOG
i'm just curious if i can search for the dir/file pattern in the single "find" command?

i want to search for the pattern "dir2/dir3/file.txt"

I'm using rhel6. Using File Browser Nautilus 2.28.4 I could easily locate any file I'm interested in by it name. I'd like to use this File Browser to locate the file name based on it content e.g. based on some word in the text file. It doesn't work for me that way ... My question: does Nautilus support the search of file based on it content or only based on the name of the file itself?
View 4 Replies View RelatedMy employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Iïve named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:
sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.

View 2 Replies View RelatedI want to append some text to the file, files are mostly big, more then 100 mb. I found the cat command, so I can create a new txt file and then append it to the original file with it. Two questions:
1. Can I append text to the file instead of creating the new file and then appending it to the original file? eg:
Code:
cat file.avi "some text" > newfile.avi
2. cat takes several seconds to execute the merging files together, it seems that it is reading the original file first, is there a way skip the reading and just append the file?

How do you append text to an entry in an existing file? For example, lets say I have a file called "env.logon" in /home/myself/bin that contains the following text:
PATH=/bin:/sbin If I wanted to add, via command line, ":/usr/bin:/usr/sbin" to the PATH= and I
used the "echo" command (echo "PATH=:/usr/bin:/usr/sbin) it would create a second entry and my file would look like:
PATH=/bin:/sbin
PATH=:/usr/bin:/usr/sbin
What I want is for it to look like:
PATH=/bin:/sbin:/usr/bin:/usr/sbin
Is there a way to get this result via command line?
