    for i in ‘input filename’
    do
    echo $i
    done

    This code will print file line by line.

    Thanks, I used this code and edited it. It’s the closest I’ve been to the output I need but for some reason using this to export each line as an individual variable isn’t working.

    Here is the script, my guess is that it’s a syntax issue of some sort. Thanks in advance for anyone who offers help! http://pastebin.com/m3472cd27

    I edited the code to input the contents of $line when ever the loop runs. it inputs line by line in a file that contains a list of id’s I pulled out of etc/passwd. for some reason it’s stops at the 25th line. it starts combining the variables to I dont’ know what’s going on. how it could work for the first 25 entries then break.

    Guys,

    I need to read a file and see for the occurence /local/svncheckout/* at the begining of each line. If this instance is found I need to delete that particular line.

    I need to write this program using shell script (bash shell)

    Thanks a lot

    Hi,
    You can try this simple code to read the file “file.txt” line-by-ine….

    while read line
    do
    echo $line;
    sleep 1;
    done < file.txt

  • anon

    Don’t listen that fool Dedeepthi ↑
    Here is the real code:
    —–cut here—————
    #!/bin/bash
    for i in ‘cat file.txt’
    do
    echo “$i”
    done
    —–cut here—————
