Eu tenho o seguinte script para monitorar alguns processos em execução:
$ cat ./print_running.sh
#!/bin/bash
ps aux | grep 'python energydata.py' | sed -r 's/\{"spectral": 0//;s/, "pp_enable.*y": 0.9,//;s/ "consumer.*ressure": 0.15,//; s/ "gamma.*//'
Quando eu o executo no terminal, recebo a saída abaixo:

O problema é quando usamos watch a lista de argumentos não aparece filtrada, então não posso monitorar os parâmetros que são interessantes para mim.
Perguntas:
watch ? Atualização:
A saída completa de ps aux sem o comando sed é uma das seguintes linhas:

Parece que tem a ver com ps truncando a saída quando em watch , veja o relógio corta a saída ps aux quando canalizado para uma explicação detalhada.
A solução é especificar manualmente a largura da coluna para ps e, em seguida, funciona mesmo dentro de watch :
#!/bin/bash
COLUMNS=2000000 ps aux | grep 'python energydata.py' | sed -r 's/\{"spectral": 0//;s/, "pp_enable.*y": 0.9,//;s/ "consumer.*ressure": 0.15,//; s/ "gamma.*//'
Tags command-line bash sed watch
