Removing last character of string
Hi ,
I have a file with the following contents in file test1.txt .
Code:
AMY_MTT_240Y001,N60_PG2_10G001,A2H_P3H_10G002,7C7_7D7_NP1,A2E_PV0_10G002,L78_PG1_64S001,A2H_P2M_NP2,LDN_YSN_64S001,WV6_WYV_64
S801,LY9_PV0_64S-R2052P,L78_PV0_64S-R2042,L78_PYE_64S-R2080,GVV_NW8_64S002,LY9_PV0_64S-UPNE1,DIS_MTP_DL72INTL,PVU_WV6_10G002,
DQE_NYY_NP6,2CS_LDN_NP1,C8L_LDN_NP1,2CS_LDN_NP2,2CS_LDN_NP3,D4O_LDN_NP1,AEQ_FR1_10G001,LDP_LE0_DL75INTL,A2H_P3H_NP2,A2H_P2M_N
P1,KS9_LDN_NP1,8BV_LDP_DL71INTL,AGA_FVP_DL71INTL,KSE_LDN_NP3,8MV_FVP_DL71INTL,8BV_FVP_DL71INTL,FV0_MTT_30N301

I want to display only those names that have "_DL" in them.

I came up with the following command:

Code:
 cat test1.txt | tr "," "\n" | grep -i _DL | tr '\n' ","

Problem with this is there is a trailing comma. I am unable to replace the trailing comma with sed or cut or head .Can anyone suggest an alternative or how to replace the trailing comma. The following is the sed i used that failed in this case
Code:
sed 's/.$//'

Thanks in advance folks

NAME

       ecaccess-file-move - Move or Rename ECaccess Files

SYNOPSIS

       ecaccess-file-move -version|-help|-manual

       ecaccess-file-move [-debug] source-ecaccess-file target-ecaccess-file

DESCRIPTION

       Allow moving an ECaccess File. When the move occurs within the same ECaccess File System then it is a rename. When the move occurs across
       two different ECaccess File Systems then first a copy is done and then a delete of the original file is done (e.g. similar to ecaccess-
       file-copy ... -erase).

       The source-ecaccess-file and target-ecaccess-file are in the form [domain:][/user-id/]path. Please read the "Shell commands -> File
       Management" section of the "ecaccess" guide for more information on the ECaccess File System.

ARGUMENTS

       source-ecaccess-file
	       The source ECaccess File name.

       target-ecaccess-file
	       The target ECaccess File name.

OPTIONS

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-file-move ec:test1.txt ec:test2.txt

       Rename the test1.txt file in the ECFS directory of the authenticated user in test2.txt.

       ecaccess-file-move ec:test1.txt home:test2.txt

       Copy the test1.txt file from the ECFS directory of the authenticated user to the test2.txt file in the $HOME directory of the authenticated
       user, then delete the test1.txt file from ECFS.
