Need help to use regex to do search and replace. Don't know how to and can't figure out how :(
Hi,
Below is an excerpt from a 20000+ lines and I want to do a search and replace of a specific string but I don't know how and I can't figure out how to. Can't find an example from Google or anywhere to do what I am wanting to do.
Code:
A 2018-11-21 08:42:17 TEST_TEST 2018-11-21 00:50:45 Accessed: 2,146,893,824 /NFS_mnt/mnlNFS111/vol_abcp_db/abcp/.snapshot/mnl1ns123_vol_abcp_db_ss.0/db/temp/abcp_temp_10.dbf
A 2018-11-21 08:41:52 TEST_TEST 2018-11-21 00:50:45 Accessed: 2,146,697,216 /NFS_mnt/mnlNFS111/vol_abcp_db/abcp/.snapshot/mnl1ns123_vol_abcp_db_ss.0/db/temp/abcp_temp_9.dbf
A 2018-11-21 03:29:04 TEST_TEST 2017-06-17 22:01:33 Accessed: 22,528 /NFS_mnt/mnlNFS111/vol_abcp_db/abcp/.snapshot/mnl1ns123_vol_abcp_db_ss.0/db/LTS/abcp_ABCD_TEST_COMM_P201406_tts_exp.dta
A 2018-11-21 03:28:57 TEST_TEST 2017-06-17 22:01:28 Accessed: 563,101,696 /NFS_mnt/mnlNFS111/vol_abcp_db/abcp/.snapshot/mnl1ns123_vol_abcp_db_ss.0/db/LTS/abcp_abcd_test_comm_201406_data_01.dbf
I need to search for all lines that contain the string /db/LTS/abcp_ but only those that ends in .dbf. So from the excerpts above, it should find the line below:
Code:
A 2018-11-21 03:28:57 TEST_TEST 2017-06-17 22:01:28 Accessed: 563,101,696 /NFS_mnt/mnlNFS111/vol_abcp_db/abcp/.snapshot/mnl1ns123_vol_abcp_db_ss.0/db/LTS/abcp_abcd_test_comm_201406_data_01.dbf
And I want to replace them so it so that it will be
Code:
A 2018-11-21 03:28:57 TEST_TEST 2017-06-17 22:01:28 Accessed: 563,101,696 /NFS_mnt/mnlNFS111/vol_abcp_db/abcp/.snapshot/mnl1ns123_vol_abcp_db_ss.0/db/LTS/abct_abcd_test_comm_201406_data_01.dbf
So, basically I need to change /db/LTS/abcp_ to /db/LTS/abct_. It is the one in BOLD that I am wanting to search and replace.
The grep regex below seems to do what I wanted. But I don't know how to do like a sed search and replace thing
P.S.:
- Is there any way to colorize or highlight certain text? I was hoping to be able to do that in this post but can't find the option to do so. I thought that option was available on the older forum ???

Hi,
I need to run a search and replace on a large database,

(1764) and I do not need those changed to ((1764))

Hi,
I'm trying to match the front and back of a sequence. It works when there is an exact match (obviously), but I need the regex to be more flexible. When we get strings of nucleotides sometimes their prefixes and suffixes aren't exact matches. Sometimes there will be an extra letter and... (2 Replies)
