There is an error in my bash script. Here, I have taken i as the variable. And I expect to have -cpi md_0_1.part1.cpt and -cpo md_0_1.part2.cpt in the first command, gmx - cpi md_0_1.part2.cpt and -cpo md_0_1.part3.cpt in the second command and so on.
Below listed are the two errors coming up:
./mdbash.sh: line 7: i: command not found
./mdbash.sh: line 11: `$i': not a valid identifier
This is the content of my script:
#!/bin/bash
#SBATCH --job_name=MD_simulation
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --cpus-per-task=20
var=$(i)
for i in {1..120..1}
do
gmx mdrun -cpi md_0_1.part$i.cpt -v -deffnm md_0_1 -noappend -cpt 1 -cpo md_0_1.part`expr $i + 1`.cpt
done
