ksh help: to remove all occurance of "/string" from every line in the file

Hanry Zhou — Sat, 12 Jul 2014 21:28:46 GMT

There are multiple lines in a file, and all look like the following:
f1:string1/string2 f2:string3/string4

f3:string5/string6 f4:string7/string8

....

I wanted to all characters with such format of "/stringx", in cluding / in the file. Would you please help me out?

Thank you!

You could use sed:

sed -e 's:/string.::g' file > file.new

I'm removing that arbitrary "x" char too.

I did not make myself clear.

/stringx, string could be any combination of of any characters or digits, it is not all the same. so, for instance,

/string1 could be "/asdbas_agd_sadf9", /string2 could be "/juhsdf_asb8bsd"

>string could be any combination of of any characters or digits

So you want to remove any combination after "/" to a space or newline?

I wanted to remove, not replace, for instance:

f1:anycharactersordigits/anycharactersdigits f2:anycharactersordigits/anycharactersordigits

f3:anycharactersordigits/anycharactersdigits f4:anycharactersordigits/anycharactersordigits

....

so, i wanted to remove "/anycharactersdigits" from every line, including "/".

so, they will become the following:

f1:anycharactersordigis f2:anycharactersordigits

f3:anycharactersordigis f4:anycharactersordigits

any characters contain letters digits, "-", or "_", no space.

f1, f2, f3.. contains any characters, digits, "-", or "_" as well, no space.

thank you!
