I would really appreciate some help into approaching this problem:
- i have a random txt file with x lines and y rows following this pattern:
ex:
- i need to telnet/ssh into these ip's, login with corresponding user, and give corresponding command.
I was thinking at a while loop, assigning for 1st line first word to $ip variable, 2nd word to $user var, 3rd word to $command variable, then execute required action and pass to next line.
Can you guys tell me if it's an easier approach than this, and how i can assign those variables based on a delimiter ?
well not yet, because :
1. i can't figure out yet how to parse every line depending on loop number (line 1 - loop 1, etc)
2. didn't yet find how to break a line based on specific delimiter
As a start you could have a look into a while-loop combined with the read command. For the field separator most shells have the variable IFS you could alter.
I'm using this piece of code to export in current.txt a text line corresponding to the sequence in the loop:
Problem is that if i run it from browser doesn't seem to work (txt file does not modify, stays the same, showing first line); in shell code works as expected.
I've tried double-quoting, single-quoting the variable without succes.
Any ideas what am i doing wrong, or another option to do this?
please solve my problem..... :(
