View 2 Replies View RelatedI am having trouble writing a script that monitors a text file. When the file contains number 1 (or any other string that is not a command) it does nothing, but when it is something different from 1, it executes that command.
So, there are 2 files: monitor.mon - this is the file that will be checked constanlty; and test.sh - the script that does the job. The monitor.mon file will have its content modified by php. This means a web page will have a form where I input commands and writes does commands in the file. Test.sh will watch when the file's content changes from character 1 to a command, execute that command and write back a 1 so it will not execute it more times.
I tried combining while and if but with no success. Tried reading the file with cat and grep -e but it doesn't seem to recognize when content changes.
write such script (bash script). I have some text file with name filename.txt I must check if this file contains string "test-string-first", I must cut from this file string which follows string "keyword-string:" and till first white-space and save it to some variable.
For example. File: PHP Code: PHP Code:
Start 15022011 Eng 12-3-42

I want to use SED to do the following: In a text file replace any occurrences of the three character string ZZZ with a quotation mark "and. replace all occurrences of a comma with a semi-colon. It is the S/ / / command which is stumping me on the first issue...inparticular how to get the replace string to be quote.

I have a line in a text file that has 40 random characters within a tag and i want to change the characters to a new set of 40 random characters (alphanumeric a-z 0-9 etc)

How would i go about doing that?
Also second question same as the above but how would i remove them instead of replacing them?
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 file with 5000 lines. it is a list of books authors, series and titles. all lines start with the author names, than there is a dash (-) than the series name, a dash again and the title of the book.
The problem I encounter is that sometime there is a series, sometime not, and as I try to enter this list in a database, I wanted to create a cvs file to import into mysql.
ex:
The best would be to be able to add in the second line, a "space dash space" just after the author name, but how to make sure it does not do it to the first line as well.
If I could separate all line with 2 dash, (grep ?) then I would be able to do a simple replace, and change the single dash into two.
What I plan to do is, create a duplicate file of a text file, and then append some text into the new text file.
View 1 Replies View RelatedI am working on a script to convert a comma seperated text file into html code line by line. The text file is like so:
Code:
link url, image url, description and I want it to output this:
Code:
<td><a href=�link url�><img src="image url" alt=�description" /></a></td>
Here is what I have so far:
Code:
#!/bin/bash
var1='<td><a href=
var2='><img src="'
var3='" alt=�thumbnail image" /></a></td>'
[code].....
It puts the entire line into the html so its no good. I'll probably need to use awk (I think).
In C++ as subjected, can anyone throw me some light on how I can generic-ly format an integer value of 1 to a string value of 0001? 11 to 0011? and 111 to 0111? simply by just appending 0 in front and limiting the length of the string to 4?

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.

I mean, this string should be removed from each line and save in another file.

View 4 Replies View RelatedI have a file called Regions.ini that looks like this:
Code:

InternalAddress = 0.0.0.0
InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = 71.171.21.9

After that I will need to compare that IP to whatismyip and if it's different then replace it but that is easy to do with sed. I just can't figure this simple hurdle out.
I have large text files with space delimited strings (2-5). The strings can contain "'" or "-". I'd like to replace say the second space with a pipe. What's the best way to go?
Using sed I was thinking of this:
sed -r 's/(^[a-z'-]+ [a-z'-]+) /1|/' filename.txt
I have created a file using open() and written data to it. Data appears as normal characters in the file. How to save these characters in a binary format in that file using C language? Here I mean that the characters should be actually stored as 0 and 1. Do I have to convert the whole data using some function or there is some standard way to do it in Linux?

View 6 Replies View RelatedI need to search a text file for a string of numbers which are different lengths, and always are between number=" and " like:

I need to grab those numbers and pipe each one to a line in a file. I've already tried something with awk and that didn't seem to work.
I've got a rather large CSV file (~700MB) which I know to consist of lines of 27-character alpha-numeric hashes; no commas or anything fancy. Somehow, during its migration from Windows to Linux (via winSCP and then a few regular SCPs), it has converted into some kind of binary format I am unfamiliar with.If I open the file in vi, everything appears fine, and it says [converted] at the bottom, although I know it's not a line endings issue (and dos2unix doesn't help). If I 'head' the file, it looks proper except for a " at the beginning of the first line. If I open up the file in nano, however, I see the at the start and then "^@" before every character (even newlines and EoF).
If I try to re-save or copy the file (say via: head file.csv > short.txt), this special encoding is preserved. I copied the first ten lines out of vi (which displays it properly) into my Windows clipboard via my SSH client, then pasted it into a new text file, test.txt. This file is visually identical when opened in vi (and similar through 'head', minus the ), although it's roughly half of the filesize. I have no idea what format this once-text file got converted to (it's notoriously hard to search the internet for symbols), but surely there must be some way to convert it back.
