I have the below lines
logs/backups
logs/backups/config_bk
logs/backups/cofig_bkp other/lines
and/some/more/lines
I have to search for a string "logs/backups" and need to delete all the lines which is having logs/backups except the first occurence... output which i need:
logs/backups
other/lines
and/some/more/lines
If the task is to preserve logs/backups
, but not logs/backups/*
, the solution is quite simple:
egrep -v '^logs/backups.' <filename>
This will filter out (-v) any line that starts (represented by a caret) with 'logs/backups' and has at least one more chracter (represented by a dot).
