HI

I have a file called 123 and say the content is

#!/bin/bash
#your name
#T1 is the name
#Example NAME=$asanka
NAME=$T1

#Your Prefix
#T2 is your title
#example TIT=$Mr
TIT=$T2

#Your Surfix
#T3 is your surname
#Example SIR=$Tom
SIR=$T3

Now by running a script say details.sh

enter your name:
enter your Tittle:
enter your Surname:

with this details how can I edit or insert T1, T2, T3 with what the user enters

regards

Asanka

I want to edit the file 123 on the fly using a script which will ask user input

bigearsbilly · 07-19-2006, 05:07 AM

Code:

echo enter your name:
read T1
echo hello $T1
perl -ip.bak "s/T1/$T1/g" file_123

This is probably better...

Script

Code:

echo enter your name:
read T1
echo enter your Tittle:
read T2
echo enter your Surname:
read T3

# redirect to new file probably best option
m4 -Uindex -DT1="$T1" -DT2="$T2" -DT3="$T3" 123 # > outputfile

TEMPLATE remove the $ (Dollar) signs first...

Code:

#!/bin/bash
#your name
#T1 is the name
#Example NAME=$asanka
NAME=T1

#Your Prefix
#T2 is your title
#example TIT=$Mr
TIT=T2

#Your Surfix
#T3 is your surname
#Example SIR=$Tom
SIR=T3

Result

Code:

billym.primadtpdev>bash asanka 
enter your name:
billy
enter your Tittle:
mr
enter your Surname:
boy  
#!/bin/bash
#your name
#T1 is the name
#Example NAME=$asanka
NAME=billy

#Your Prefix
#T2 is your title
#example TIT=$Mr
TIT=mr

#Your Surfix
#T3 is your surname
#Example SIR=$Tom
SIR=boy
