I have a file a.txt and I want to find slashes(/ and \ ) in it, so I used this command in my a.ksh script slashcheck=cat a.txt | grep '/'.

but how do I check for '' backward slash at the same time?

CodePudding user response：

Please try with:

cat a.txt | egrep '(\/|\\)'

CodePudding user response：

you can try this: cat a.txt | grep "[\/]"

Try using a regular expression. You could use something like grep -E '[/\\]'.

Note that you will need two backslashes because the first one masks the second one.

Using squared brackets allows any character in these brackets to be a match.

The -E stands for extended and allows regular expressions to be used as seach patterns.
