常用脚本收集

Power shell查看文件夹大小

PS D:\0work> Get-ChildItem |

Format-Table -AutoSize Mode, LastWriteTime, Name, @{ Label="Length"; alignment="Left"; Expression={ if($_.PSIsContainer -eq $True) {(New-Object -com Scripting.FileSystemObject).GetFolder( $_.FullName).Size} else {$_.Length} } };

log文件过大，单独收集其中关键数据，例如Pxx

import re

def main():

    input_file = "log.lammps"

    output_file = "Pxx.data"  ####

    with open(input_file, "r") as f_in, open(output_file, "w") as f_out:

        data_start = False

        step_index = -1

        pxx_index = -1

        for line in f_in:

            if "Step" in line and "Pxx" in line:   #####

                headers = line.strip().split()

                step_index = headers.index("Step")

                pxx_index = headers.index("Pxx")

                data_start = True

                continue

            if data_start:

                if line.strip() == "":

                    data_start = False

                    continue

                if re.match(r'^\d', line.strip()):

                    values = line.strip().split()

                    step = values[step_index]

                    pxx = values[pxx_index]

                    f_out.write(f"{step} {pxx}\n")

if __name__ == "__main__":

    main()
