Making 256 files with variables

Shell Programming and Scripting
1

Hi,

I am really sorry for posting a newbie question here, but I do not have time to start learning shell scripting at the very moment.

My question is how can I write a script what takes a file with a variable number, changes the variable number to a new number and saves the file as a new file. I have 4 variables in one file and I need to change all of them four times.

That means all together I will have 4^4=256 new files and doing it manually just takes too much time.

Thank you in advance,

Mario

PS. If you have time could you explain what different rows do aswell, so I don't have to bother you guys again if I have something new to work with :smiley: .

Are you expecting like this.

See the following code, I am creating file name as variable value.

 var1=Welcome;
 eval >$var1

I didn't understand, what I need to change 4 variables for four times.

Hei, it's not exactly what I meant.

I will paste my file here, tho it is quite long. I added X, Y, Z, and M for the numbers I want to change.

Each letter (X,Y,Z,M) must be a number (60; 150; 240; 330). So I have 4 places where there could be 4 different numbers. All together I have 4^4 different files I want to have.

I hope it made the question easyer :slight_smile: .

Thank you in advance,

Mario

Not really sure your question, here is just a start.

The code finds out the lines which first column end of 7, and replace the last column.

awk '$1~/7$/ {$NF=($NF~"X")?"60":$NF;$NF=($NF~"Y")?"150":$NF;$NF=($NF~"Z")?"240":$NF;$NF=($NF~"M")?"330":$NF;}1' urfile

Hello, mario8eren:

If the file with the letters to be substituted is called "template", the following script will create 256 files in the current directory. The name of each file indicates the values that were substituted for each letter:

#!/bin/sh

template=$1
for values in {60,150,240,330}\ {60,150,240,330}\ {60,150,240,330}\ {60,150,240,330}; do
    set $values
    X=$1; Y=$2; Z=$3; M=$4
    sed "s/X\$/$X/;s/Y\$/$Y/;s/Z\$/$Z/;s/M\$/$M/" "$template" > "X$X-Y$Y-Z$Z-M$M"
done

Sample run (I did verify that proper substitutions were made in a few random files, but I did not inspect each one nor code something to verify):

$ ./mario8eren.sh template
$ ls
X150-Y150-Z150-M150     X240-Y150-Z150-M150     X330-Y150-Z150-M150     X60-Y150-Z150-M150
X150-Y150-Z150-M240     X240-Y150-Z150-M240     X330-Y150-Z150-M240     X60-Y150-Z150-M240
X150-Y150-Z150-M330     X240-Y150-Z150-M330     X330-Y150-Z150-M330     X60-Y150-Z150-M330

Hey guys, I ran into another problem today, if I add some lines to the script it works, but if I add another part it gives me an line syntax error. I coloured the non-working part red:

#!/bin/sh

template=$1
for values in {60,150,240,330}\ {60,150,240,330}\ {60,150,240,330}\ {60,150,240,330}; do
    set $values
    X=$1; Y=$2; Z=$3; M=$4
    mkdir "X$X-Y$Y-Z$Z-M$M"
    cp script ./"X$X-Y$Y-Z$Z-M$M"
    sed "s/X\$/$X/;s/Y\$/$Y/;s/Z\$/$Z/;s/M\$/$M/" "$template" > ./X$X-Y$Y-Z$Z-M$M/"X$X-Y$Y-Z$Z-M$M"
    cd ./X$X-Y$Y-Z$Z-M$M
    babel -igzmat "X$X-Y$Y-Z$Z-M$M" -oxyz coord.xyz
    source $USELIB/tm510
    x2t coord.xyz > coord
    define <<EOF


    a coord
    ired
    *
    *
    eht



    scf
    iter
    300

    dft
    on

    ri
    on

    *
    EOF

    qsub script
    cd ..
done

Thank you again in advance,

Mario

Little update, I added the "define part" of the file into another sh script and used sh command in the first script, so everything is working now as I wanted it.

Thank you all again :slight_smile: .
