Data get the NF of a string line
Hi all,

New here and new to shell as well.
Currently I have a problem when use echo $1 | awk -F\| '{print NF}' to get the NF of input string separated by "|". There's input contains more than 100 fields, then I have error awk: record `dd|14/06/2003|ssssss...' has too many fields . What do I solve this problem?

Thanks

Use gawk, or try...
Code:
echo $(($(echo $1|tr -dc '|'|wc -c)+1))

Question Get field value.
since the awk can't handle 100+ fields. what do I use to get one of the field value, say field 45. Currently I am using
Code:
echo $1|awk -F\| '{print $45}' .

And I don't know why I can't get gawk command in my environment.

Thanks

Try...
Code:
oldIFS=$IFS
IFS='|'
set $1
IFS=$oldIFS
echo $#
echo ${45}
