Answer 1

awk 中的一个:

$ cat foo.awk
BEGIN { FS=OFS="|" }  # set separators
NR==1 { nf=NF }       # expect the field count to be correct on header record
NF<nf {               # if NF less than on header record
    while (NF<nf) {   # and while NF < less than on header record
        b=$0          # buffer too short record
        getline       # read next record
        $0 = b $0     # catenate buffer and fresh record
    }
} 1                   # output

运行它:

$ awk -f foo.awk foo
DeptID|EmpFName|EmpLName|Salary
Engg|Sam|Lewis|1000
Engg|Smith|Davis|2000
HR|Denis|Lillie|1500
HR|Danny|Borrinson|3000
IT|David|Letterman|2000
IT|John|Newman|3000

如果记录增长太长则不检查。
