    You can also use touch command to create empty files:
    touch foobar.txt

    Detailed information but would appreciate if someone can upload the solution for cat command as in executing or running the vi program. I am writing a finction in the vi and want to execute it outside the vi on the bash shell.

    Thx- Nitish Anand

    please help me. mail on nehra13@gmail.com

  • Nitish Anand Dec 23, 2007 @ 12:36

    !wq for save and exit VI
    !w to just exit.

  • chakjoy Feb 24, 2008 @ 3:35

    have two files, ‘file1’ and ‘file2’.
    file1 has:
    1234
    4567
    6789

    file2 has:
    abcd
    efgh
    ijkl

    would like to combine into one like:
    1234 | abcd
    4567 | efgh
    6789 | ijkl

    Please give direction.

    Thanks

      Hi,
      @chakjoy

      here is an solution. Using arrays:

      #!/bin/bash
      declare -a ARRAY1
      declare -a ARRAY2
      let count=0
      let count1=0
      while read LINE
      do
      ARRAY1[$count]=$LINE
      ((count++))
      done < file1.txt
      while read LINE
      do
      ARRAY2[$count1]=$LINE
      ((count1++))
      done < file2.txt
      for((i=0; i<${#ARRAY1[@]};i++));do
      echo "${ARRAY1[${i}]} | ${ARRAY2[${i}]}"
      done

      I hope this help.

    Hi chakjoy,

    Did u manage to resolve your problem? Try the folling link if thats what you meant:-

    OR

    cd /var/log && ls -al
    this switches to the /var/log directory if the directory change was sucessfuly it will then list the contents of that directory.

    You can also list the contents of a directory without leaving your current location..

    ls -al /var/log
    Would list the contents of /var/log no matter your current location in the directory tree.

    You can also use | to send the output of one command to the input of another..

    mount | column -t
    Show mount points in a column format

    ls -al | grep *.jpg
    List the contents of a directory buit only show files ending in .jpg

    ps aux | grep X11
    List processes but only show processes containing X11 > and list.txt
    Will list the contents of the /var/log directory and save it in the file list.txt

    hope this helps

    ====================

    You can chain copmmands together using &&

    cd /var/log && ls -al
    this swithces to the /var/log directory if the directory change was sucessfuly it will then list the contents o fhte directory.

    just to add to that, you can likewise chain commands together with the || operator (OR operator, not to be confused with a pipe | )

    Code:
    $ cd /mnt || cd /varthis would attempt to change to the /mnt directory. If it could not it would then switch to the /var directory. If the cd /mnt command was successfull then it would stop. Similarly,

    Code:
    $ cd /blah || cd /homeit’s probably safe to say there is no /blah directory on your computer so typing this command would attempt to change to a non-existant directory, fail, and consequently change to /home
    have fun!

    There is so much to learn when you get inside of linux, for example, VI is not the easier text editor but it rocks xD

    Perhaps a subliminal mistake, looks like you used ‘cat foot.txt’ instead of ‘cat foo.txt’ in your example.

    I am trying to maintain a list of “ROMS” be it NDS, or MAME, no matter.
    Instead of accessing each page on a website, is it possible to use cat to look for say; title” … ” within .aspx on the website and copy it to local txt file ? I have been using ..
    cat wordlist/* | tr -cs A-Za-z ’12’ | tr A-Z a-z | sort | uniq > wordlist/masterlist.txt to merge numerous txt files into one, have them sort, and no repeats. something like this to be able to input the website start & end page and where to save the roms list.. there doesn’t really seem to be any 1 site that has a complete & accurate list. I an not trying to circumvent anything to get to the roms, I merely wish to be able to goto a webpage, enter in the variables, run a script to gather the list from the site, then after I have done this to a few sites run the above quoted, to merge the different sites into 1 ( hopefully ) accurate list so I know the names & numbers of the roms for each list.

    How do you edit the file you created ?

    • 🐧 nixCraft Oct 6, 2013 @ 8:45

      Use a text editor such as vi/emacs/joe and more.

  • Ray Sep 19, 2013 @ 20:11

    Great, but I found a typo:

    To display file contents, type
    $ cat foot.txt

    It should be foo.txt not foot.txt.
