Code:
sed -n '/user1/p' server.out

What is server.out ? I'm guessing its lines are too long. Is it really a text file? Binary files can cause this error.

You don't need to use cat here, but that's unrelated to your error.

does the line begin with user1? does it end with it? do you have a sample line that includes this user1 record? Will user1 always be lower case or could it be mixed case?

And as Corona688 said, you don't need to cat the file first. A simple grep will suffice. Simplify the command as well:

Code:
grep -i user1 server.out

sysconf LINE_MAX will show the line limit for UNIX tools. It used to be a default 2048 bytes on older systems,.

Hi.

On systems like:
Code:
OS, ker|rel, machine: Linux, 3.16.0-4-amd64, x86_64
Distribution        : Debian 8.6 (jessie)

This may work:
Code:
getconf Query system configuration variables (man)
Path    : /usr/bin/getconf
Type    : ELF 64-bit LSB executable, x86-64, version 1 (SYSV ...)
Help    : probably available with --help

Such as:
Code:
$ getconf LINE_MAX       
2048

Best wishes ... cheers, drl

So what is a satisfactory resolution?

Do you wish to create line breaks -- add newlines -- in the file?

Do you wish to simply look at the neighborhood of the matched pattern?

If the latter, command bool may be able to help:
Code:
bool    print context matching a boolean expression (man)
Path    : ~/executable/bool
Type    : ELF 64-bit LSB executable, x86-64, version 1 (SYSV ...)
Help    : probably available with [     ]-h,--help
Home    : https://www.gnu.org/software/bool/

Best wishes ... cheers, drl
