I can't understand sed error output.
Hey forum,

I have a problem with a script what used to work, but suddenly is not working anymore. I have been trying different things for an hour now and I give up Smilie .


Code:
#!/bin/sh

asukoht=`pwd`
template=$1
for values in {2.0,2.5,3.0,3.5,4.0,4.5,5.0,5.5,6.0,6.5,7.0,7.5,8.0,8.5,9.0,9.5,10.0}; do
    set $values
    X=$1
    mkdir "$X"
    sed "s/X\$/$X/" "$template" > ./$X/"coord"
    cd ./$X
#    sh ../define.sh
#    sh ../cosmoprep.sh
    cd $asukoht
done

The template file is in the same directory as the script.

Code:
[TM510] mario8@fermi84 (konf1karbo) >ls
alg-coord~  coord.xyz  cosmoprep.sh  defineerija_lahus.sh  defineerija_lahus.sh~  define.sh  template  template~

And the error output is:

Code:
[TM510] mario8@fermi84 (konf1karbo) >sh defineerija_lahus.sh
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory
sed: can't read : No such file or directory

I don't understand, because everything is in order imo.

Thank you in advance Smilie .

You want to vary a value "$values" in the for-loop. The variable "$values" is never used any further - are you sure this is what you want?

Presumably the line X=$1 should read X=$values, but this would raise the question why to bother with a variable "X" when you could use the variable "values" equally.

I hope this helps.

PS: it often pays to add a few lines printing some variables contents in a loop to understand what goes wrong and how.

Hi,

I think the problem is the '$template' variable. It has no value and 'sed' expects it. Here:
Code:
template=$1
...
sed "s/X\$/$X/" "$template" > ./$X/"coord"

I hope it helps.

Regards,

I need to create multiple files with different inputs (the template file).

Anyway, thanks for your help. I took the
Code:
asukoht=`pwd`

command away from the script and it started working Smilie . Thanks for your anwsers Smilie .

You could use a default value if no parameter like
Code:
template=${1:-template}
