I want to grep 2 patterns in a file on Solaris UNIX.
That is grep 'pattern1 OR pattern2' filename.
The following command does NOT work:
grep 'pattern1\|pattern2' filename
What is wrong with this command?
NOTE: I am on Solaris
614
To search multiple files with the grep command, insert the filenames you want to search, separated with a space character. The terminal prints the name of every file that contains the matching lines, and the actual lines that include the required string of characters. You can append as many filenames as needed.
What operating system are you on?
It will work with on systems with GNU grep, but on BSD, Solaris, etc., \| is not supported.
Try egrep or grep -E, e.g.
egrep 'pattern1|pattern2'
