I'm trying to write a shell script which finds bits of data from a text file. at the moment i'm using grep and basically i need a function which will look through the text file and take the data out of it. the file has days, months, years etc and i want it so i can type feb 06 and it finds all of the data for feb 06.
the problem i have is i can type feb and all the information comes back for feb, but i can't get it more precise e.g. feb 2009 and it finds just feb 2009, it seems to ignore that latter half. I've tried experimenting with egrep and having two inputs but i can't seem to fuse them together, it only takes the first input.

I'm having a slight dilemma on reading data from a text file and outputting it into a table then displaying it. Basically I'm writing a shell script that takes information from text files then outputs the data into a table with 4 headings.he extracting of the data is fine, but creating a table i'm having problems with. I think it is possible to do it using the awk function, but so far i'm having a lot of difficulties.
i have custom programs written in Basis pro5. Standard output to a pdf virtual printer works fine. Using pdftk to overlay on to a form is hit or miss.... There are products out there like Unform that are just too expensive for my company. i have purchased another product from a company that prints the forms to the laser perfectly but i am incapable of capturing them and saving them as pdf's for archiving/emailing/faxing and i don't much care for this company.

I am writting a program that reads a text file (music.txt) & stores it in a Data Structure. I am a novice learning over the internet so I this is something I have never done. How do I do this?

Write a program that reads the data from the music.txt file and store it in a data structure. To implement this data structure you must use an array of songs and each song must be represented by a struct with appropriate fields. So far all I can do is open to file to read it (very simple I know) but so far is it correct?
Im trying to figure out how to display parts of a .db file created by the scorch2000 server to display a player name, games played, score and maybe more...

" > logfile.txt : gives an error extra character after the "
2- logsave logfile.txt 'send "show command;
" ': error invalid command
3- i simply tried to send the output of the whole script to file logsave /home/logfile ./script : seems that logsave work under root only
4- ./script > logfile : the problem with this is that the output of echo or (read "enter your id") command will not be displayed on the screen (actually nothing will be displayed, i have to open the log file to see the output). is there any way to save the log of the "send" ? or to save the log of the complete script without hiding the output on the screen?
I need a loop that pulls out the user name into a variable and then pulls out the LastUpdate field into another variable so I can then perform a comparison against the last update field. Requirements are AIX tools including AWK, SED and Perl I am writing a script to check AIX users password expiration dates and if they are within the alerting period (ie. 7 days etc) it will email the user. I will release the full script into the public domain once completed. The text file I want to parse is formatted like:

I have a toshiba phone system that has a feature where it spits raw data and i can direct that data to a serial port on the toshiba phone system or to an IP/PORT the data is just ascii data - tells me calls that are made/time/etc
I would like to setup an existing linux box to capture this data and store the data for me
then later i can build reports based on that data (and for me a report could be just a few cat's/greps/etc so basic stuff) - but i can figure this out later.
for now i would just like to GRAB the data on a port and dump it into a file (and recycle files every 24 hours)
I have an application where I am sending data via serial port from PC1 (Java App) and reading that data in PC2 (C++ App). The problem that I am facing is that my PC2 (C++ App) is not able to read complete data sent by PC1 i.e. from my PC1 I am sending 190 bytes but PC2 is able to read close to 140 bytes though I am trying to read in a loop.Below is code snippet of my C++ AppOpen the connection to serial port
I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:
