Read multiple text file in shell sccript

Hello, I have a file named file_1.sh that I want to duplicate into file_2.sh, file_3.sh,..., etc. I also need to change the text within each file so that it would fit the file name. For example, in file_1.sh there is a command to save some output as 'output_1.txt', and also there is an input range of 1-100.

I have four files that look like this:

file_1:

Code: a b c d e f file_2:

Code: g h i j k l file_3:

Code: m n o p q r file_4:

Code: s t u v w x I would like to write the sum of the 3rd column in each line of every file such that my new output files has 4 columns (4th column similar for all files) as follows:

file_1:

Code: a b c c+i+o+u d e f f+l+r+x file_2:

Code:

When a Linux server is serving many concurrent requests to read many different files, does it:

Seek to File_1, read the entire file, then seek to File_2, read the entire file, then seek to File_3, etc etc Seek to File_1, read part of it (up to the readahead value?), then seek to File_2, read part of it, then seek back to File_1 where it has left off, read more of it, then seek to File_3, etc, et

Say I have the following structure on path origin_path

origin_path/X=1/B/file_1.txt origin_path/X=1/B/file_2.txt origin_path/X=1/B/file_3.txt ... origin_path/X=2/B/file_1.txt origin_path/X=2/B/file_3.txt origin_path/X=2/B/file_3.txt ...

origin_path/X=10/B/file_1.txt origin_path/X=10/B/file_3.txt origin_path/X=10/B/file_3.txt ... ...

where there is more than one folder under X=1, X=2, etc.

I assign the variable

Code: name=`find .

Hello, I have a situation where I want to change a line of text in multiple files, but the problem is that I want to change the text to something unique for each file.

For example, let's say I have five files named bob.txt, joe.txt, john.txt, tom.txt, and zach.txt. Each of these files has a line (1st line) with the text "name = xxx".

Help. My script is working fine when executed manually but the cron seems not to catch up the command when registered.

The script is as follow:

#!/bin/sh

for file in file_1.txt file_2.txt file_3.txt do awk '{ print "0" }' $file > tmp.tmp mv tmp.tmp $file done

And the cron job I am making is:

*/2 * * * * /root/folder/test.sh

Thanks for the help.
