使用sed或python将所有反斜杠替换为正斜杠

Question

aim: to replace all backslashes with forward slashes.

actual string:\\\\test.abc.com\\path1\\path1_1\\123\\ubntu

expected string://test.abc.com/path1/path1_1/123/ubntu

trying to get sed to work for the above is turning out to be quite a task

any thoughts?

Edit: read as Env variables in Jenkins The Complete use case being: They are passed as Windows UNC Paths via jenkins, need to be mounted on Unix

In Python on *nix

It behaves differently when tried via variables!, when i read the variables via python, the '\\' string is chopped of by the interpreter. i have tried repr(variable) in conjunction with .decode('string_escape') but to no avail. raw_input() does not help in python on unix

here is main the python script named test1.py

s=re.sub(r'\\',r'/',repr(sys.argv[1].decode('string_escape')), Which is run as python test1.py \\test.abc.com\\path1\\path1_1\\123\\ubntu ,Output of which is turning out to be //test.abc.compath1path1_1123ubntu; Why is python thinking '\\' cannot be displayed :-( –

Trying via sed now through env variables.

Answer 1

You can use other tools but translating characters is the job tr was created for:

$ tr '\\' '/' < file
//test.abc.com/path1/path1_1/123/ubntu

Answer 2

Updated for environment variables.

You say that the path is in an environment variable (let's say UNC_PATH), so in Python:

# test.py
import re, sys

s = re.sub(r'\\', r'/', sys.argv[1])
print s

and invoke it like this:

$ UNC_PATH=\\\\test.abc.com\\path1\\path1_1\\123\\ubntu
$ python test.py $UNC_PATH
//test.abc.com/path1/path1_1/123/ubntu

For sed, do this:

$ echo $UNC_PATH | sed -e 's/\\/\//g'
//test.abc.com/path1/path1_1/123/ubntu

Original answer

With sed:

$ echo '\\test.abc.com\path1\path1_1\123\ubntu' | sed -e 's/\\/\//g' 
//test.abc.com/path1/path1_1/123/ubntu

In Python:

>>> import re
>>> s = re.sub(r'\\', r'/', r'\\test.abc.com\path1\path1_1\123\ubntu')
>>> print s
//test.abc.com/path1/path1_1/123/ubntu

Answer 3

Through sed,

$ sed 's~\\~/~g' file
//test.abc.com/path1/path1_1/123/ubntu

Through Python,

>>> import re
>>> s = r'\\test.abc.com\path1\path1_1\123\ubntu'
>>> print s
\\test.abc.com\path1\path1_1\123\ubntu
>>> m = re.sub(r'\\', r'/', s)
>>> print m
//test.abc.com/path1/path1_1/123/ubntu
