Suppose we have this data file.
john 32 maketing executive
jack 41 chief technical officer
jim 27 developer
dela 33 assistant risk management officer
You can use simple awk like this:
awk '{$2=""}1' file
However this will have an extra OFS in your output that can be avoided by this awk
awk '{sub($2 OFS, "")}1' file
OR else by using this tr and cut combo:
On Linux:
tr -s ' ' < file | cut -d ' ' -f1,f3-
On OSX:
tr -s ' ' < file | cut -d ' ' -f1 -f3-
