I am pretty new to bash scripting...I am trying to write a script that will take an input and read it word for word and then DO something with it like echo. I have been able to find how to read word for word from a file but I don't know how to do it with input.
I was looking for something like
Code:
exit 0 The input would be A-Z a-z 0-9 and have a single space between each word.
Well, I am facing one issue:How can i read two files word by word at a time using any loop as i need word by word comparision in shell script?Please let me know pseudo code.
I have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has its contents a single word, say wordone)
Code: #!/bin/sh for f in value.txt do echo $f done
so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?
I have grepped a log file to obtain every line that contains a word (let's call it 'blah'). I now want to only display a list of entries within that search result that feature the word 'host' anywhere in the line, and I also want to display the single word *after* 'host' (up until the next space). So, the end result will look like this:
Want to search for ~ and delete it as well as to append the entire line to the above line. For Ex:
1111xxxx date Sandy area is ~around this area.3222xxx date There seems to ~left side of map, the colours are accurate (showing green areas)Even if I ~zoom in, the green parks, xxx3258 date The dammed up ~away, the "other" body of water varies ~blackNatural gas leaching.
IT MUST LOOK LIKE:
1111xxxx date Sandy area is around this area. 3222xxx date There seems to left side of map, the colours are accurate (showing green areas)Even if I zoom in, the green parks, xxx3258 date The dammed up away, the "other" body of water varies blackNatural gas leaching.
In formsweb.cfg file are two lines with labels archive_jini= and archive= at the beginning of line. After equal sign (=) is row of filenames of java archives delimited by coma(,). When I insert a new jar file in java directory, I have to append the very same name of jar file to both lines if that name is not yet present.
As I'm starting to learn bash scripting I'm trying to automatize some tasks I usually perform. I have a notification mail I need to send several times a day. It has this structure:
Quote:
Dear user, blah blah blah blah
You need to contact the following people:
[code]...
To replace "user", I found this:
Code:
read -p "Please enter username: " username echo "Dear $username,"
Which probe to be very useful with other simple notifications like this. But I don't know how to manage the email addresses as they are usually more than one and could vary from 1 to 10. They should appear one above the other. I found this: "Here is a little work around. The only thing the user needs to do is hit enter without anything else on a line and it will close out"
Code:
#!/usr/bin/ksh word=a until [[ $word = "" ]];do
[code]....
I tried to use it and modify for my needs but I failed, I don't realize yet how can I use it. If possible, I would like to use the until loop like the above example just for learning purposes but any other form will be accepted as well.
How can I move around the bash commandline efficiently?In the Windows prompt, one can go back or forward one word by pressing ctrl and <-/->.What's the equivalent in a bash environment?
I built the indexes, but when I search I get this: Top-Level Documentation Application Manuals
openSUSE Documentation (en) Htdig error: Unable to read word database file '/home/philip/.kde4/share/apps/khelpcenter/index//opensuse-manuals_en.words.db'
[code]...
the UNIX manual pages work, the Application Manuals show nothing, and the openSUSE Documentation shows the same error. This is the same no matter what I search for.
Here's a challenge I've been struggling for months with:
I have a bash script that reads URL addresses of our internal server and then executes some test commands on them. Something like this:
Code: read -p "Enter URL: " url sh execute-what-ever-to $url
After copy-pasting the URL the user taps the enter key and the script proceeds, but here comes the tricky part: I want this to work without the need to press the enter key after copy-pasting the URL.
"read -n" does not work in this case, as the URLs vary greatly in length. However, the URLs always end to the same string. They could be like "http://url1/END", "http://url2/END" and so on. So this ending string "END" could be theoretically used to recognize that the whole URL has been pasted.
In linux is there a way to find the next word of a particular word of a file. grep displays entire line of the particular word. But i want only the exact next word of that particular word.is there any command for that.
I'm building a script for my place of employment. The next step in it is checking what the user input was. Determining if they added a part in there or not. The script prompts for a hostname. Hostnames are localhost.localdomain. Now, I want the script to check to see if they put localdomain and if they did, not to add the domain to the /etc/sysconfig/network, but just what they entered. So say the user inputs:
I have a large tab delimited text file, about 17gb. It only has 6 column. On column number 4, it is all numbers. Ranging from 1-1000. I want to count how many times each number occured. So the output I want is in 2 columns, first one is a number, second column is how many times it occured. I tried
head -n 1000 coverage | cut -f 4 | uniq -c
Didn't work for me, the first column returned is not unique.
How to find a word from different files in linux ? Is there any command like (find . / -name *****), that can search files in the system for a particular word in Linux?
ive searched around about this for a bit, but have been unable to find a working and suitable solution for me to do, what i require is to be able to change a string such as:hIs Is a TeSt to --> This Is A Test - AND place it in a variable - so far ive only succesfully been able to make the whole sentence uppercase or lowercase.

As you can see i would like the output file to be just the dogs, not the otehr information. But because the information is mixed up how can i extract only the dogs? (i cant do and awk '{print }' because the dogs are found in colounm 2 or 3 or sometimes even 4.
