Quick script for running repetitive commands

david_ross · 01-18-2004, 11:02 AM

I just thought I'd post this incase anyone else found it useful. I wrote it mainly to save typing out users and hosts for ssh connections but left it so it could be used for running any sort of command.

All you need to do is put the floowing script into a file called "/usr/local/bin/go", or anywhere else in your path.

Code:

#!/bin/bash

if [ -r ~/.go ] && [ ! $1 ];then
  OLDIFS=$IFS
IFS="
"
  num=0
  choice=1
  while [ $choice -lt 1 ] || [ $choice -gt $((num-1)) ];do
    a=1
    num=1
    echo "          Please choose a command number below"
    for line in `cat ~/.go`;do
      if [ $a -eq 1 ];then
        command[$num]=$line
        a=2
      else
        echo "          $num) $line"
        a=1
        num=$((num+=1))
      fi
    done
    echo -n "          Enter your selection: "
    read choice
    echo
    IFS=$OLDIFS
    ${command[$choice]}
  done
else
  echo You do not appear to have a \~/.go config file or it is not readable
  echo \~/.go files should consist of 2 lines, the first being the command
  echo and the second being the description that is used by the go script.
  echo

fi

Then make it executable:
chmod 755 /usr/local/bin/go

You then need a basic configuration file called ".go" in your home directory. The file takes the structure:

Code:

command 1
Description of command 1
command 2
Description of command 2

and so on... You should end up with a file like

Code:

ssh root@server.mydomain.com
SSH as root to my server
ssh webmaster@server.mydomain.com
SSH as webmaster to my server
/home/user/backup.sh
Run backup script

I hope you find it useful

Very nifty. I don't actually have a use for it at the moment, but I'll come up with one (or many) and find it very useful, I'm sure.

It was cool to see and to try to figure out what was going on. Forgive me if I'm totally missing the boat or screwing stuff up but I made a mod for typos or other brain damage in blue (I need those kinds of error-checks because I make a lot of mitsakes.) Thanks for sharing! (I wish more people would post stuff like this.)

Code:

#!/bin/bash

if [ -r ~/.go ] && [ ! $1 ];then
  OLDIFS=$IFS
IFS="
"
  num=0
  choice=1
  while [ $choice -lt 1 ] || [ $choice -gt $((num-1)) ];do
    a=1
    num=1
    echo "          Please choose a command number below"
    for line in `cat ~/.go`;do
      if [ $a -eq 1 ];then
        command[$num]=$line
        a=2
      else
        echo "          $num) $line"
        a=1
        num=$((num+=1))
      fi
    done
    echo -n "          Enter your selection: "
    read choice
    if [ $choice -ge $num ] || [ $choice -eq 0 ];then
      echo "That is not an available option."
    else
      echo
      IFS=$OLDIFS
      ${command[$choice]}
    fi
  done
else
  echo You do not appear to have a \~/.go config file or it is not readable
  echo \~/.go files should consist of 2 lines, the first being the command
  echo and the second being the description that is used by the go script.

Nice addition. I tend not to do that much error checking when I write something for myself but It's good to have - I'll update my local version too

digiot, if your interested in another useless script then here is another.

Ok a quick edit. I've added a bit of colour coding just for the hell of it:

Code:

#!/bin/bash

if [ -r ~/.go ] && [ ! $1 ];then
  OLDIFS=$IFS
IFS="
"
  num=0
  choice=1
  while [ $choice -lt 1 ] || [ $choice -gt $((num-1)) ];do
    a=1
    num=1
    echo -e "\033[0;36m          Please choose a command number below:\033[0m"
    for line in `cat ~/.go`;do
      if [ $a -eq 1 ];then
        command[$num]=$line
        a=2
      else
        echo "            $num) $line"
        a=1
        num=$((num+=1))
      fi
    done
    echo -ne "\n\033[0;36m          Enter your selection:\033[0;33m "
    read choice
    if [ $choice -ge $num ] || [ $choice -eq 0 ];then
      echo -e "\033[0;31m          That is not an available option.\033[0m\n"
    else
      echo -e "\033[0m"
      IFS=$OLDIFS
      ${command[$choice]}
    fi
  done
else
  echo You do not appear to have a \~/.go config file or it is not readable
  echo \~/.go files should consist of 2 lines, the first being the command
  echo and the second being the description that is used by the go script.

The color's a nice touch. I really like it when color's used, partly because it looks good but mostly because it does make it easier to read when done right, like that.

Thanks for pointing me to that second script. That's a great example of potentially getting a *lot* done relative to the size of the script. I always like any sort of 'preservation/backup/times of disaster' script.

I'm very much a beginner and not very good at this. And for some reason I get as much or more out of checking out a 'live' script as reading a whole chapter of a tutorial. Educational and useful.

Very good. I am going to use this . Thanks .
