Shell script

Shell Programming and Scripting
1

I have one script.

#!/bin/ksh
[[ $# -lt 1 ]] && echo "Usage: $0 pattern (pattern can be gsx name or trunkgroup or point code)" && exit 1
egrep -h "$1" /appl/voip/voipfiles/trunkgroups/tglastrun.mostrecent

Which works like this.

./abc.sh <input>

I have one requirement.

  1. if input is Point code like 203-53-27

do this

else

that.

means. I want to control function of script based on input.

How to identify if input is any Point code or else any word like tcm or CIRCU.

I want script to identify input whether it's its point code or not. if it's point code do something, else in any other case of input do that.

---------- Post updated at 06:38 PM ---------- Previous update was at 06:35 PM ----------

in case of point code i want exact match.

Like

egrep -h "$1" /appl/voip/voipfiles/trunkgroups/tglastrun.mostrecent|grep -w "$1"

using -w it matched exact.

in case of other input (not point code ) I want this to function like normal grep.

Like

egrep -h "$1" /appl/voip/voipfiles/trunkgroups/tglastrun.mostrecent

What do you exactly mean by "Point code"? Is it always XXX-XX-XX where all the X's are integers? (3 X's-2 X's-2 X's)

Hi gacanepa,

Input to the script can be PointCode or word.

./abc 209-57-73

./abc tcm

./abc SHOKCA0

I want script to identify $1 that command line input and do operation based on that.

If script identifies $1 is Point-code then it will do certain function, else it will do other function.

I just want one one if - else script.

I don't know how script will identify if it's PointCode or some thing else.

---------- Post updated at 07:28 PM ---------- Previous update was at 07:25 PM ----------

one logic to the find the input will be like this, if Input starts with an integer or not.

If starts with integer
do this,

else
do this.

This does the job:

#!/bin/bash
glob="[[:digit:]][[:digit:]][[:digit:]]-[[:digit:]][[:digit:]]-[[:digit:]][[:digit:]]"
if [[ ${1} == $glob ]]; then
    echo "yes"
else
    echo "no"
fi

This is called "Character classes" and you can find a good tutorial here.
Let me know if you have further questions.

Hi Gacanepa.

Thanks for reply, little improvement required numbers can be 1 to 3 it's not 3x-2y-2z

I tried something, but not able to match correctly.

bash-3.2$ cat raza
#!/usr/bin/bash
Input="$1"
echo "$Input"
if [[ "$Input"="[0-9]+-[0-9]+-[0-9]+" ]];
then
echo "HELLO"
PC=`echo "$Input" |sed -e 's/^[0]*//g'|sed -e's/-[0]*/-/g'`
grep -hw "$PC" /appl/voip/voipfiles/trunkgroups/tglastrun.mostrecent
else
echo "Hi"
grep -h "$Input" /appl/voip/voipfiles/trunkgroups/tglastrun.mostrecent
fi

bash-3.2$

Point code can be 209-78-125 , 27-67-85, 209-127-56 like this.
So please improve it.

Please use code tags. It makes your code more understandable - I'll be more than glad to help :).

7 
 bash-3.2$ cat raza
#!/usr/bin/bash
Input="$1"
echo "$Input"
if [[ "$Input"="[0-9]+-[0-9]+-[0-9]+" ]];
then
echo "HELLO"
PC=`echo "$Input" |sed -e 's/^[0]*//g'|sed -e's/-[0]*/-/g'`
grep -hw "$PC" /appl/voip/voipfiles/trunkgroups/tglastrun.mostrecent
else
echo "Hi"
grep -h "$Input" /appl/voip/voipfiles/trunkgroups/tglastrun.mostrecent
fi
bash-3.2$

don't know how to use code tag. Just tried this, hope it is fine.

My test criteria in If statement is not working well.

8 
#!/bin/bash
echo "You provided the following argument: $1"
if [[ $1 =~ ^[0-9]{1,3}-[0-9]{1,3}-[0-9]{1,3}$ ]]
then
    echo "yes"
else
    echo "no"
fi

This script uses regular expressions:

[0-9]{1,3}

means: "allow a minimum of one and a maximum of three digits between 0 and 9".
