How I can replace this command --need help
Hi,
can I delate first line in a file without opening a file. Normal unix "sed -i '1d' $path/cash.log" command is working fine, but my windows application not supporting latest version of sed, I also tried to download latest version of sed.exe but failed to find one. I am in a process of implement a buffer mechanism using following script #!/bin/sh path=C:/APPS/Tivoli/bin/w32-ix86/TME/TEC/scripts set -x exec 2> $path/SMS_LOG1.log Cash_count=`more $path/cash.log |wc -l` while [ "$Cash_count" != "0" ] do sms=`head -1 $path/cash.log` echo "#MSG#$sms" >>$path/output sleep 5 sed -i '1d' $path/cash.log Cash_count=`more $path/cash.log |wc -l` #echo "Cash_count: $Cash_count" done < $path/cash.log Please help me on this. Thanks in advance Regards Sudhish |

Deletion of first line is the problem
Hi,
Let me explain my requirement 1. $path/cash.log is a cash file, I can’t rename it because it content is loaded by another script 2. This script will send SMS until cash.log file become empty also it will continue check for the messages, start sending sms as soon as the message comes 3. Script can only take first line of the cash.log file and send SMS 4. Then I have to delete the first line, other wise script will always send same message only Deletion of first line is the problem Thanks in advance Sudhish |
