how to deal with " Input/output error " when you initiate input/output error kali linux any commands in Linux.

disk or someone hacked your machine. In this situation first suggestion would be to check /var/log/messages for any disk related alerts (might see some sense key alerts). tail -n 100 /var/log/messages tail -f /var/log/messages If you notice any disk issues , try any disk utility to confirm this. One option would be use smarttools. You can check smartool option
Linux Input Output Error Deleting File
to fix bad blocks. If you already installed it you can take the advantage of that. Next immediate action would be take backup of your system. Good if you already have it :-). If you have good backup its safe to reboot.If your system was hacked there are chances they might messed up your file and system would not work after reboot. You can also try fsck but it really dont fix most time if it bad block issue. Fsck can fix only if it related to any filesystem related issues. Usually fsck will fail in between as when it try to read the file at bad block. Now if try to reboot , it can also give the same output. You can try init 6. # reboot bash: /sbin/reboot: Input/output error # shutdown -r now bash: /sbin/shutdown: Input/output error If the above reboot commands doesnot work try either forced reboot or shutdown . Forced Reboot echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger Forced Shutdown echo 1 > /proc/sys/kernel/sysrq echo o > /proc/sysrq-trigger Y

Check also /var/log/messages.

Updated June 19, 2016 Every process in Linux is provided with three open files( usually called file descriptor). These files are the standard input, output and error files. By default : Standard Input is the keyboard, abstracted as a file to make http://www.linuxtechi.com/standard-input-output-error-in-linux/ it easier to write shell scripts. Standard Output is the shell window or the terminal from which the script runs, abstracted as a file to again make writing scripts & program easier Standard error is the same as standard http://askubuntu.com/questions/181972/what-does-intermittent-input-output-error-suggest output:the shell window or terminal from which the script runs. A file descriptor is simply a number that refers to an open file. By default , file descriptor 0 (zero) refers to the standard input & often abbreviated as output error stdin. File descriptor 1 refers to standard output (stdout) and file descriptor 2 refers to standard error (stderr). These numbers are important when you need to access a particular file , especially when you want to redirect these files to the other locations, File descriptors numbers go up from zero. Redirecting Standard Output Syntax to redirect the output of a command to a file. # Command_options_and_arguments > output_file Example : linuxtechi@localhost:~$ cat /proc/cpuinfo > command.txt We can see the input output error data that would have gone to the screen with more command : linuxtechi@localhost:~$ more command.txt processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 37 model name : Intel(R) Core(TM) i3 CPU M 370 @ 2.40GHz stepping : 5 microcode : 0x616 cpu MHz : 0.000 cache size : 6144 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 5 wp : yes The > operator tells the shell to redirect the output of the command to the given file. If the file exists , the deletes the old contents of the file and replaces it with the output of the command. Redirecting a Command's Input : Syntax to redirect the input of a command to come from a file. # Command_options_and_arguments < input_file Use the < operator to redirect the input for a command , example is shown below : linuxtechi@localhost:~$ wc -l < command.txt 52 In this example , the input to the ‘wc‘ command comes from the file named command.txt. The shell sends the contents of the file command.txt as a standard input for the wc command. Note : We can also combine both redirectio

Sometimes the computer freezes and then unfreezes 2 minutes later, and other times when I try a basic command like less I get the error bash: /usr/bin/less: Input/output error. But this is intermittent too. Any suggestions? Also if I try sudo reboot and enter my password, I get sudo: unable to open /var/lib/sudo/plato/7: Read-only file system Before I used to be able to do sudo reboot fine. If I tail /var/log/syslog I do see these curious lines: .... ata1: softreset failed (device not ready) .... ata1: hard resettting link .... ata1: link is slow to respond, please be patient (ready=0) What can I do to fix this? 12.04 share|improve this question edited Aug 29 '12 at 21:38 asked Aug 29 '12 at 21:31 dan 97521831 I suggest you have a look at /var/log/syslog, and I have a hunch you'll see a lot of disk-related errors. Input/output error indicates that the system is having trouble reading or writing information, and this is most likely due to damaged storage devices. –roadmr Aug 29 '12 at 21:36 2 Go to "Disk utility", it will tell you more about the "health" of your hard drive. –Cumulus007 Aug 29 '12 at 21:44 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote Backup your data NOW.
