Question

这是我试图运行的内容：

Argument list too long

这是我得到的错误：

import timeit
import os
import inspect, importlib as implib
import textwrap as twrap

def src_modules(filename):
    assert (len(filename)>1)

    mod = implib.import_module(filename.split(".")[0])
    ml_alias = []
    ml_actual = []
    ml_together = []
    ml_final = []
    for i in inspect.getmembers(mod, inspect.ismodule):
        ml_alias.append(i[0])
        ml_actual.append((str(i[1]).split(" ")[1]))
        ml_together = zip(ml_actual, ml_alias)
    for t in ml_together:
        (a,b) = t
        ml_final.append(a+":="+b)

    return ml_final

def l_to_str(itr):
    assert(len(itr)>0)

    itr.sort()
    r_str = ""
    for i in itr:
        r_str += i+"  "
    return r_str

def src_info(filename, start_time=timeit.default_timer()):
    assert (len(filename)>1)

    filename_in = filename
    filename = filename_in.split(".")[0]

    if __name__ == filename:
        output_module = filename
    else:
        output_module = __name__

    print ("\n" + (80 * "#"))
    print (" runtime ~= {0} ms".format(round(((timeit.default_timer() - start_time)*1000),3)))
    print (" source file --> '{0}'".format(filename_in))
    print (" output via --> '{0}'".format(output_module))
    print (" modules used in '{0}':".format(filename))
    print ("  "+"\n  ".join(twrap.wrap(l_to_str(src_modules(filename)), 75)))
    print (80 * "#")

    return ""


if __name__ == "__main__":
    src_info(os.path.basename(__file__))


## how to use in X file:
#
# import print_src_info
# import os
#
# < ... your code ... >
#
# if __name__ == "__main__":
#     print_src_info.src_info(os.path.basename(__file__))


## example output:
#
# ################################################################################
#  runtime ~= 0.049 ms
#  source file --> 'print_src_info.py'
#  output via --> '__main__'
#  modules used in 'print_src_info':
#   'importlib':=implib  'inspect':=inspect  'os':=os  'textwrap':=twrap
#   'timeit':=timeit
# ################################################################################

基本上我想要计算目录中有多少文件中包含特定字符串。

我已经看到了与此错误相关的几个问题，但他们似乎都没有专注于事后计算结果。任何建议将不胜感激。

Answer 1

您当前目录中的文件可能太多。

您可以find使用-exec选项：

find . -maxdepth 1 -type f -exec grep 'this is a test' '{}' + | wc -l

grep的参数太多了？
