General :: Write A Bash Script That Will Read The Word From The Text File?
Jun 10, 2011
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 want to write a bash script to parse a text file with the following lines and set variables for each line so that I can use them in the rest of the script.
Timestamp=123456789
Company=ABC Company
Server=Server
Recipient=Joe Smith
Email=joe@abc.com
simplest way to read each line one at a time for everything before the =, set that to a variable name with the value equal to everything after the =

I have a script almost working except for 1 thing. What I'm trying to do is read a file that has the files that need to be FTP'd using a bash script. I have everything working except the reading of the file. It works outside of the ftp script I've wrote but once I put it in the FTP script it doesn't.
Here's the Script:
#Here's where the problem is that I know of
I've been playing w/ the exclamation points to see if that could be the problem, but so far no luck.

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.

At the moment I got my md5sum checking working which I write to a text file and see below.
If the md5sum works it will write the output to check2.md5 test.txt: OK
If the md5sum fails it will write test.txt: FAILED
How do I write if statement to check the output whether or not the md5sum failed or not ?
check1="/home/ops/Desktop/test1/check1.md5"
check2="/home/ops/Desktop/test1/check2.md5"
cd /home/ops/Desktop/test1
md5sum test.txt > $check1

I need to chop of the top 30ish lines of several log files until a line starting with "Initialization completed."The trouble is that it's not always the same amount of lines that need to be deleted, and they don't always contain the same information, which is why I would need to delete everything priorhe line starting with "Initialization completed."Right now I have a little script I wrote based on looping each file through several "grep -v" commands with each known pattern of lines I want to ignore, but it is tedious and I have to inspect each file afterwards to make sure nothing is left from above "Initialization completed

How do i disable the linux file cache on a xfs partition (both read an write).
We have a xfs partition over a hardware RAID that stores our RAW HD Video. Most of the shoots are 50-300gb each so the linux cache has a hit-rate of 0.001%.
I have tryed the sync option but it still fills up the cache when copinging the files. ( about 30x over per shoot :P )
/etc/fstab:
/dev/sdb1 /video xfs sync,noatime,nodiratime,logbufs=8 0 1
Im running debian lenny if it helps.

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.
