How to count number of columns in a pipe delimited file?
There are only 4 fields, first field is “0|1” To fix that, a proper CSV (or delimited file) parser should be used, such as one in Perl: As a note, simply fixing an awk or sed solution with a convoluted RegEx won’t work easily, since on top of pipe-containing-and-quoted PSV fields, the spec also allows quotes as part of the field as well.
When do you use pipe delimiter in SAS?

When does a pipe in a CSV file break?
Every one of these solutions – as well as those on other answers – do NOT work 100%! Namely, they all break when it’s a REAL “pipe-separated” file, with a pipe being a valid character in the field (and the field being quoted), the way real CSV files work.
How to count number of columns in a comma delimited file?

You can work around that by using a subshell or with a function (Bourne/POSIX version) like: An alternative solution is $ (ls -d — * | wc -l). If the glob is *, the command can be shortened to $ (ls | wc -l).
Which is the output format for tab delimited file?
It works for any single character separator that is NOT a double quotation mark, meaning standard tab delimited, CSV, etc. formats (as standard as they get anyway…) The output format is merely illustrative and a bit decorative at the end, but the content is still useful IMHO, such as handling multiple files.
