I have a string like $(SOMETHING) and want to remove '(' and ')' in a script file. How can I do that? I read that sed command is a filtering utility but don't know how to use it.
View 12 Repliesi use this script to get the time and date of back and fourth transactions for a particular execution id. I use a substr command on the 5th column to to cut the milli seconds off the time value. - otherwise the times would look like 08:30:04.235
grep <executionID> <auditfile> | awk '{ print $1, $2, $3, $4, substr($5,1,8}
FIX -> Mon 3/1/2010 08:30:04
FIX <- Mon 3/1/2010 08:32:36

anyhow - i append two sed commands to further clarify the direction of the message.
awk '{ print $1, $2, $3, $4, substr($5,1,8} | sed -e 's/->/ ->IN/g' | sed -e 's/<-/<-OUT/g'
FIX -> IN Mon 3/1/2010 08:30:04
FIX <- OUT Mon 3/1/2010 08:32:36
[code]....
I tried using an awk gsub () command within the string instead of the two seds, but it did not work:
awk '{ print gsub(/<regex>/, <replace with>,$1), $2, $3, $4, substr($5,1,8}
the sed works ok, but it would be cooler to make the replacement within the awk command:
gsub(/->/,-> IN, $1)
Is there a way where i could replace the value of the $1 column in the awk print string?
Let me *try* and explain what I'm trying to do, and keep in mind aside from a little command line stuff I'm a beginner to any of what I'm asking about.
I have a directory structure something like this:
Code:
/usr/local/chatlogs/
webserver1/
1.chatlog
2.chatlog
[Code]....
So that whatever was captured in the () in the first part of the statement would be used in the 1 in the back part of the statement for every n.chatlog that might be in any of the /webserver directories at that time.

View 2 Replies View RelatedI have a LAMP server set up (under Ubuntu 10.04 64-bit), and have a PHP application running on the Apache2 server. I copied the "default" website setup, and created a new one with the root at "/home/kota/WebRoot/".
When running my PHP application though, I come across a major issue: The script doesn't seem to be able to modify any files that are currently on the system, or create new ones.
However, this limitation is restricted to when running through Apache2. In other words, if i run it by typing "php5 myapplication.php" from the terminal, it works without a flaw. This leads me to believe that there is a permissions issue, disallowing Apache2 to create and modify files anywhere on my system.
Although it shouldn't make much of a difference, here is the basic information that I feel I should provide:

If I have a word in a text file and I need to replace it by another word (for example, i need to replace abc by fff) so what is the command I can type it?
I am using vi editor.
I have a String that I would like to sign using a given RSA Private key. I thought this would be relatively easy but I have not been able to find out how to do it, unless I'm looking to far into a simple problem. Do i have to put the string into a file, and sign the file, or can i just sign the string/message?

and file abc.log on server 2 has string "test" 4 times.then the output will beStringName : Countexampletest : 6 timesNote : I have created the password less connectivity using ssh-keygen.

View 1 Replies View RelatedI am trying to do this:
1. Read csv delimited file line1 and store all values in array
2. Use the values stored in the array and replace values in other text file with them
3. read line2 in the cvs file and repeat the process
4. Do above for all lines in the cvs file
for example:
file1.cvs content:
text1,text2,text3,"text 4"
a1,a2,3,"a 4"
file.txt content:
some text $array1$ some text
some text $array2$ some text
1. read line 1 - text1,text2,text3,"text 4" put each value in array X[] lines that contain spaces in cvs will have double quotes
2. read x[1] and replace value $array1$ (in file.txt) with x[1]read x[2] and replace value $array2$ (in file.txt) with x[2] and so on
Can above be accomplished in BASH and how?
I would like to know how I can replace a string in one file with the complete contents of another life.
View 10 Replies View RelatedI need to do some text file manipulation which I think should be done with standard commands in BASH. I'm looking at comma seperated text files (stock market data). It comes in the form of date, stock code, open, high, low, close, volume. What I need to do first is move all data with same stock code sequentially into individual files.
While doing this since the stock code will now be the file name I need to remove the stock code. Next I need to filter out overlapping data from different files with the same date. ie. where two files contain the same date on the one line only one line will be added to the combined file. I think there must be a tutorial out there for basic text manipulation like this, I just haven't found it yet.
I am trying to remove all the files in a directory hierarchy which a certain string inside the file (not the file name, it is the file content).
I can list out all the file name which has a string in the file using 'grep -r -l mystringlooking for'.
But how can I remove all the files returned by the grep ? I am trying this on ubuntu.
I am searching for Class declaration on a site with hundreds of PHP files, how can I do this in the current folder and subfolders using GREP?

I am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:
OLD_STRING='<property name="webServiceHost">${jboss.bind.address}</property>'
NEW_STRING='<!--<property name="webServiceHost">${jboss.bind.address}</property>-->'
