I have:
datafile contains 1234567890
>wc -c datafile | awk '{print $1}'
>11
The program
#!/bin/ksh
let n = (wc -c datafile | awk '{print $1}')
echo $n
I expect n to be 11 but it gives error message. What is wrong with this statement?
Thanks! (3 Replies)

coverpg
make.coverpg(1) mgetty+sendfax manual make.coverpg(1) NAME
make.coverpg - create a fax coverpg on stdout SYNOPSIS
make.coverpg [options] <pages> <sender-ID> <sender-NAME> <receiver-ID> <receiver-NAME> <date> <time> DESCRIPTION
make.coverpg is called from faxspool(1) to generate a cover page for the just-processed fax. It has to create a proper G3 file (e.g. via pbm2g3(1) or hp2hig3(1) or ghostscript(1)) and output that on stdout. If the program doesn't exist, or can't be executed, the fax simply won't get a coverpage (so, if you don't want a fax coverpage, do not install it...) make.coverpg can put anything it wants on the page, but note that there are certain legal requirements in certain countries about the con- tents that *have* to be on the cover page, for example, the fax phone number of the sender and the recepient, the number of pages, or simi- lar things. make.coverpg gets the informations about the fax to be sent from the command line, in the order listed above. If the environment variable normal_res is set to something non-empty, faxspool requests that make.coverpg creates a cover page in normal resolution (98 lpi). Default is fine resolution (196 lpi). NO make.coverpg program is installed by default, since everyones needs differ too wildly. Some sample coverpage programs are provided in the mgetty source tree, in the samples/ subdirectory (coverpg.pbm shows how to do it with "pbmtext|pbm2g3", coverpg.ps shows how I do it with ghostscript). In this directory, you can also find two shell scripts (fax and faxmemo) that will take advantage of one more esoteric feature of my cover- page programs: if called with the option "-m <memo-file>", the sample programs will put a text file "<memo-file>" on the cover page (used for short notes or such). To make use of it, faxspool is called with the option '-C "make.coverpg -m <memo-file>"' (the double quotes are needed!). OPTIONS
none Example A five-page fax sent from me to my second number could result in a call like this: make.coverpg 5 "+49-89-3243328" "Gert Doering" "3244814" "myself" "Sep 15 94" "22:10:00" FILES
