awk -F";" -v url=$url -v nr=$nr 'NR==nr{$2=url$2}1' file
Why do I get the output
field1 field2
instead of
field1;field2
I have given -F";", so the field separator should surely be ";". (1 Reply)

iofileb.d
iofileb.d(1m) USER COMMANDS iofileb.d(1m) NAME
iofileb.d - I/O bytes by file and process. Uses DTrace. SYNOPSIS
iofileb.d DESCRIPTION
This prints a summary of requested disk activity by pathname, providing totals of the I/O events in bytes. It is a companion to the iofile.d script - which prints in terms of I/O wait time, not bytes. I/O wait time is a better metric for understanding performance issues. Both disk and NFS I/O are measured. Since this uses DTrace, only users with root privileges can run this command. EXAMPLES
Sample until Ctrl-C is hit then print report, # iofileb.d FIELDS
PID process ID CMD process name KB kilobytes of disk I/O FILE file pathname DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver- bose descriptions explaining the output. EXIT
iofileb.d will sample until Ctrl-C is hit. SEE ALSO
