General :: Parse File From Remote Server To Caculate Count Of String Existence In That File?
Aug 30, 2010
I need to parse the file of same name which exist on different servers and calculate the count of string existed in both files.Say a file abc.log exist on 2 servers.I want to search for string "test" on both files and calculate the total count of search string's existence.For example if file abc.log on server 1 has string "test" 2 times
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.
I have a cron job running to act upon files if they exist in a folder... the problem is the nature of those new files. New files aren't put there very often, the server isn't used much (most of the time) so I would like to not check every minute to see if a new file is there and allow the disks to spin down and go to sleep. However, when a new file does exist there, it needs to be acted upon ASAP.
So currently I'm handling that with a cron job... it works... but what would work much better is the ability to act upon the event of a new file being present. Is there a way to trigger action upon new file system activity in a certain path? or just keep doing what I'm doing and have the system check all the time and keep the disks awake just in case something shows up?
I need to parse through a file which contains timestamps of transactions. What I am trying to do is come up with a Max Transactions Per Second (TPS) value. I was thinking that creating an array variable would be the way to go, but I'm having problems determining even how to start.
I am working on the script to parsing the specific message like "aaaa" in multiple log files like N1-***,N2-***,N3-***..The script is to find the list of lof files which contains the message "aaaa" and export the list into excel filE.
Anybody know and command to count any characters in file? I would like to know the total number of character " (quote) in file. My idea is to check if in a script the total number of this character is pair.
I want to write a bash script to parse a text file with the following lines and set variables for each line so that I can use them in the rest of the script.
Timestamp=123456789 Company=ABC Company Server=Server Recipient=Joe Smith Email=joe@abc.com
simplest way to read each line one at a time for everything before the =, set that to a variable name with the value equal to everything after the =
I have a log file that contains information like this:
---------------------------- r11141 | prasath-palani | 2010-12-23 16:21:24 +0530 (Thu, 23 Dec 2010) | 1 line Changed paths: M /projects/ M /projects/
[code]....
what i need is, i need to copy the data given between the "---" to seperate files, for, e.g. the first set of data between the "---" should be in one file and another set of data in another file.
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.
I have a utility that works with files. The utility is crashing at after about 120 files. The input to the utility is a file containing a filelist. I want to cut the file with the file names in it to seperate files containing about one hundred or so. My thought was to determine the number of lines/100 and then use head and delete to create temporary files to run the utility multiple times to prevent the crash. When I tried to create a variable using the wc -l command the output gives me the number of total lines but it also includes the filename of the input file. (873 Filename.txt) I can not figure out how to remove the Filename.txt from the variable.
i need to count the number of files and put the output into a variable. i used wc -l filename but i couldnt find an option to put the output to variable. example if the number o line is 5, i need the output of echo $x is 5.
I am trying to grep a particular string from the files of 2 different servers without copying and calculate the total count of its occurence on both files. File structure is same on both servers and for reference as follows:
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.
