More simple bash scripts

Script for start X session automatically, after making login ( without using any login manager)

#!/bin/bash
if (($(ps -A | grep -c X) > 0));
then
        echo starting X....;startx;
fi

 do
        unzip "$file"
done

Script to get links from an list every X time, for example, usefull to automatically open download links like rapidshare, netload, megaupload,...
Changing time and application, it can be useful to do lots of things =)

#!/bin/bash
waitTime=3600
app="/usr/bin/firefox"

cat $1 | while myLine=`line`
do
 echo "Requesting" $myLine
 $app $myLine;
 sleep $waitTime && echo ""
done

Mount FTP as filesystem

CurlFtpFS is a filesystem for accessing FTP hosts based on FUSE and libcurl.

[Install]

localhost ~ # emerge net-fs/curlftpfs in gentoo
localhost ~ # apt-get install curlftpfs in ubuntu/debian
localhost ~ # ./configure && make && make install by the manual way

[Mount]

localhost ~ # modprobe fuse if you dont have fuse module loaded
localhost ~ # curlftpfs ftp://user:pass@site.com /mnt/mountpoint

[Umount]]

localhost ~ # fusermount -u /mnt/mountpoint

Thats it, now you can access with any file explorer like konqueror, nautilus…..we can do almost everything like edit source code

Adding on fstab
curlftpfs#ftp.host.com /mnt/mountpoint fuse rw,uid=500,user,noauto 0 0

or Making alias
alias mHost=’curlftpfs ftp://user:pass@site.com /mnt/mountpoint’

localhost ~ # sshfs user@site.com: /mnt/mountpoint use “-o allow_other” for share between multiple users

[Umount]

localhost ~ # fusermount -u /mnt/mountpoint

Thats it, now you can access with any file explorer like konqueror, nautilus…..we can do almost everything like edit source code, create, delete….

Adding on fstab
sshfs#USERNAME@REMOTE_HOST: REMOTE_PATH MOUNT_POINT fuse SSHFS_OPTIONS 0 0

Simple text extraction from images

You must have an screenshot tool and an OCR tool, the tools i use is imagemagick to take screenshots and gocr to recognize characters.
