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?

General :: Bash Script That Read From File And Ping Remote Host

Feb 13, 2011

Q=What will this do?
A=This will read from /root/Desktop/iplist (or anywhere you want to put the list) after it reads the ip it will ping the ip two times. If the remote host is up then it will write the ip to a log. If the ping fails it will display it on the screen, write the ip to syslog so that you can do remote logging, and last it will send the ip by email to a user or a group of users.

Code:
#!/bin/bash
#wrote by Zach Underwood feb-12-2011
#test and wrote on centos 5.5 with sendmail
rm -f /root/Desktop/iplog #This will remove the good iplog
exec 9</root/Desktop/iplist #put full path the file where ip list is. Make sure that the ips are listed one per line.
while read -u9 ip
do
ping -c 2 $ip > /dev/null 2> /dev/null # ping and discard output
if [ $? -eq 0 ]; then # check the exit code
echo "$ip is up" >> /root/Desktop/iplog #write the ip of the hosts that are up
else
echo "$ip is down" # will show on the screen the ips that are not up
logger -p auth.notice "$ip is down" # will write the down host to syslog
echo "$ip is down" | mail -v -s alert user@anydomain.com > /dev/null 2> /dev/null #will send mail users about host down
fi
done

General :: Mount - Disable Read And Write File Cache On Partition?

Feb 8, 2011

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.

General :: Permissions - Manually Mount A File System Read/write As A Normal User?

Oct 6, 2010

I want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.

I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.

Ubuntu :: Error Creating File System: Helper Exited With Exit Code 1: Cannot Open /dev/mmcblk0p1: Read-only File System

May 2, 2010

I bought a new SD card which I intend to put some MP3s on - except that I can't write to it because it tells me the destination is Read Only. No-probs thinks I: I'll just reformat it.

"Error creating file system: helper exited with exit code 1: cannot open /dev/mmcblk0p1: Read-only file system"

Various chmod commands all result in Read-only file system. I tried umount then mount commands, but it couldn't find it to mount once I'd unmounted it using the same /media/ file path (I assume it's the only one).

Ubuntu :: Edit File Permissions - Read / Write Access

May 6, 2010

I have apache2 running on my computer. I want to change the permissions for /var/www/ so that I can edit the files without a problem. Right now I can use the gksudo command, but I'd like to be able to have all the files available when using an IDE like eclipse.
I've read in several places that
Code:
chmod 755 /var/www
will do, but if I'm not mistaken that would give read/write access to anyone. I'm not in a production environment, so I'm not too worried about security, but I'd like to give anyone else as less permissions as possible. Would this be possible?

Ubuntu Networking :: Home File Server - Read / Write Compatibility

Jan 30, 2011

I've been a Xubuntu/Ubuntu/Lubuntu hobby user for about 18 months now. I started using Linux as a way to revive older computers provide a backup and expand my knowledge of computing. The command line was something new to me but as long as I can find detailed directions on how to do what I want I can usually manage. I set up a Samba server for my home shared network and now I'd like to make the shared drives of that server accessible from outside my network. Via ssh or ftp or some program of the like. I'd like to have it user name and password protected. Configurable user rights would be nice. (read/write/delete/etc) As well as novice user friendly.

My end goal is a server with read/write capability that I will be able to access from work or a friends house or anywhere with an Internet connection and my laptop. I understand about port forwarding and have done so with my home network behind an AT&T U-verse router/modem. I've researched openssh and some ftp setups but they seem like they can be difficult. Now for the questions. Is this task something that can be accomplished without a degree in computer networking? Is there a program(s) that would make this a simpler task? Is this more complex than its worth? How would I go about setting up such a thing?
