The
zsh
offers a wide variety of possibile features to simplify command-line usage. If you're interested in a more user-friendly shell, look at ohmyzsh. It is easy to install and offers a wide variety of usability improvements, like better tab completion, integrated git status messages and so on. If you're interested in one of these, put them in your
~/.zshrc
. Here are some useful functions for
zsh
, specific to Slurm-HPC-systems.
Auto-completion for scancel
function _scancel {
SQUEUE_OUTPUT=$(squeue -o "%i:%j" -u $USER | grep -v "JOBID:NAME")
SCANCEL_COMMANDS=(
'--signal=:Signal type (USR1, USR2, INT etc.)'
'--batch:Send signal to all batch steps'
)
while IFS= read -r line; do
if [[ ! -z $line ]]; then
SCANCEL_COMMANDS+=("$line")
fi
done <<< "$SQUEUE_OUTPUT"
SCANCEL_COMMANDS_STR=$(printf "\n'%s'" "${SCANCEL_COMMANDS[@]}")
eval "_describe 'command' \"($SCANCEL_COMMANDS_STR)\""
}
compdef _scancel "scancel"
Auto completion with lmod/ml
function _ml {
ML_COMMANDS=(
'-t:Show computer parsable output'
'unload:Unload a Module'
'spider:Search for a module'
'avail:Show available modules'
'list:List loaded modules'
)
ML_COMMANDS_STR=$(printf "\n'%s'" "${ML_COMMANDS[@]}")
eval "_describe 'command' \"($ML_COMMANDS_STR)\""
_values -s ' ' 'flags' $(ml -t avail | sed -e 's#/$##' | tr '\n' ' ')
}
compdef _ml "ml"
ftails
When using this, you will be able to follow jobs more easily. If you have just one sbatch job running, and enter
ftails
, it will automatically follow that one job. If you have more than one running, it will prompt you (via whiptail) which job to choose. It also adds
slurmlogpath
, which, when called like
slurmlogpath $SBATCH_ID
will print the log path to stdout.
function slurmlogpath { scontrol show job $1 | grep StdOut | sed -e 's/^\s*StdOut=//' }
function ftails {
JOBID=$1
if [[ -z $JOBID ]]; then
JOBS=$(squeue --format="%i \\'%j\\' " -u $USER | grep -v JOBID)
NUMBER_OF_JOBS=$(echo "$JOBS" | wc -l)
JOBID=
if [[ "$NUMBER_OF_JOBS" -eq 1 ]]; then
JOBID=$(echo $JOBS | sed -e "s/'//g" | sed -e 's/ .*//')
else
JOBS=$(echo $JOBS | tr -d '\n')
JOBID=$(eval "whiptail --title 'Choose jobs to tail' --menu 'Choose Job to tail' 25 78 16 $JOBS" 3>&1 1>&2 2>&3)
fi
fi
SLURMLOGPATH=$(slurmlogpath $JOBID)
if [[ -e $SLURMLOGPATH ]]; then
tail -n100 -f $SLURMLOGPATH
else
echo "No slurm-log-file found"
fi
}
Alias for squeue -u $USER
Sometimes one has to know which jobs are still running and this is done by
squeue -u $USER
. This is tough to type, and writing
sq
for that is easier.
alias sq="squeue -u $USER"
