I'm trying to output two certain fields of a very large text file to 2 very small text files. Then take those files and add all the lines together to come up with a total from each file (two totals).
Here's what I've got:
Code:
#!/bin/bash
echo "0" > /media/in.txt
echo "0" > /media/out.txt
[code]....
Breakdown: Put 0 in a text file to be drawn by respective while loops for math later
Output last 60 integers to a file for total A (new integer every minute)
Output last 60 integers to a file for total B (new integer every minute)
The two while loops are supposed to be adding the lines together. The echo commands at the end are for testing purposes, just to see the output. However, when I run this, I get the output of
Code:
0 0
Which is obviously not what it's supposed to be. Is there a more efficient way to do this or am I missing something in the script that would reset the values to "0"?
I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.

The wrong lines are not all together in a block but randomly distributed so I need to make a loop checking if the line is in the other file and if it is, replace it.

After installing skype from rpm I wanted to add a skype repo for future updates. As root I did 'touch skype.repo' and tried to open by 'kwrite skype.repo' but get the undermentioned error. As a user I can open the empty file with the command 'kwrite skype repo' but cannot save it as I am informed that I only have read access.
Code:
[root@localhost yum.repos.d]# kwrite skype.repo

I have a script that among other things generates a makefile with an error that causes make to fail. specifically, the string "-Wimplicit-function-dec" should be changed a bit to "-Wimplicit-function-declaration". Is there a way to have bash add the new eight characters in the right place (on line 105)?

View 1 Replies View RelatedI'm looking for a way to insert the number of lines in a file to the start of the aformentioned file. This should be simple but as I am not used to scripts in Linux, I am finding it tough going. I can find the number of lines in a file easily enough via
filesize=$(awk 'END {print NR}' $1)
but as for inserting this into the first line, i'm failing to do so. I've tried some of the other approaches on these forums but none so far have been able to do so.
I've tried:
sed '1i$filesize' $1
but sed i requires a string, not a variable so no go I've also tried:
mv "$1" "${1}.bak" 2>/dev/null || touch "${1}.bak"
cat $filesize "${1}.bak" >"$1"
but again with no luck as cat seems to need an input stream Just to recap, i want to insert a line at the start of a given file that holds the number of lines the original file has.
ie the file:
a
b
c
d

should become:

1/a

View 2 Replies View RelatedFor example, I have a file called "file" like this one:

type=strongsubj len=1 word=unique pos=adj stemmed=n priorpolarity=neutral
type=strongsubj len=1 word=absolutely pos=adj stemmed=n priorpolarity=neutral

type=strongsubj len=1 word=purecolor pos=anypos stemmed=n priorpolarity=negative
type=strongsubj len=1 word=accusingly pos=anypos stemmed=n priorpolarity=negative
I want to add the plural for the noun, for example if find this line:
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
will add one more line :
type=weaksubj len=1 word=friends pos=noun stemmed=n priorpolarity=positive
where we add "s" for the word friend
I did try to do like that:
<code>
cat file | while read LINE ; do
set -- ${line}
if [[ "${4#pos1=}" == "noun" ]];then
#I tried this line but it doesn't work properly:
v3==$(echo $line |sed 's/$3/$s') #I want to find the third word "word=friend" in that line and add "s" after that word
# I don't know what command to add this new line "$v3" to the file ???

Every now and then I have to indent the lines in my script to 4 space characters. I generally do it line by line. Is there an automated command in vi using which I can indent some set of lines to desired number of space characters in one go.
