Non-empty standard error or non-zero ## exit code cause cancellation of the print request. ## ## Calling sequence: ## ## slow.filter prefix file1 file2 ... fileN ## ## "prefix" is prefix of full path name for output files. All we ## do is append a ``-k'' for k = 1, 2, ..., N. ########## ##### # # Most of the time we don't want the standard error to be captured # by the Spooler, mainly to avoid "Terminated" messages that the # shell puts out when we get a SIGTERM. We'll save the standard # error channel under another number, so we can use it when it # should be captured. ##### exec 5>&2 2>/dev/null ##### # Error message formatter: # # Invoke as # # errmsg severity message-number problem help # # where severity is "ERROR" or "WARNING", message-number is # a unique identifier, problem is a short description of the # problem, and help is a short suggestion for fixing the problem. ##### LP_ERR_LABEL="UX:lp" E_IP_ARGS=1 E_IP_OPTS=2 E_IP_FILTER=3 E_IP_STTY=4 E_IP_UNKNOWN=5 E_IP_BADFILE=6 E_IP_BADCHARSET=7 E_IP_BADCPI=8 E_IP_BADLPI=9 E_IP_BADWIDTH=10 E_IP_BADLENGTH=11 E_IP_ERRORS=12 errmsg () { case $1 in ERROR ) sev=" ERROR"; ;; WARNING ) sev="WARNING"; ;; esac # tag=`expr "${LP_ERR_LABEL}" : "\(.*\):"``expr "${LP_ERR_LABEL}" : ".*:\(.*\)"` echo "${LP_ERR_LABEL}: ${sev}: $3 TO FIX: $4" >&5 } prefix=$1 shift k=1 for file in "$@" do if [ ! -r "${file}" ] then errmsg ERROR ${E_IP_BADFILE} \ "Cannot read the file \"${file}\"." \ "See if it still exists and is readable, or consult your system administrator." else 0<${file} 1>${prefix}-${k} eval "2>&5 ${FILTER}" || { exit_code=$? while [ 127 -lt "${exit_code}" ] do exit_code=`expr "${exit_code}" - 128` done exit ${exit_code} } fi k=`expr "${k}" + 1` done
