Example use: lets say you want to grep a file for the string -v - normally -v will be considered the option to reverse the matching meaning (only show lines that do not match), but with -- you can grep for string -v like this: 用例:假如你想grep一个文件来查找-v字符串,通常-v会...
给定一个密钥字符串S,只包含字母,数字以及 ‘-’(破折号)。N 个‘-’ 将字符串分成了 N+1 组。给定一个数字 K,重新格式化字符串,除了第一个分组以外,每个分组要包含 K 个字符,第一个分组至少要包含 1 个字符。两个分组之间用 ‘-’(破折号)隔开,并且将所有的小写字母转换为大写字母。
The problem can be simulated by generating dummy data as follows: test_df<-data.frame(a=c(1:50000),b=c(1:50000),path=do.call(paste0,Map(stri_rand_strings,n=50000,length=c(100,50,7),pattern=c('[A-Z]','[0-9]','[A-Z]')))test_latest_ver<-test_df$path[sample(50000,2000...
<PATTERN> A regular expression used for searching. To match a pattern beginning with a dash, use the -e/--regexp flag. For example, to search for the literal '-foo', you can use this flag: rg -e -foo You can also use the special '--' delimiter to indicate that no more flags ...

5. Prints Number of Lines Around Match The grep’s-Coption is similar, but instead of printing the lines that come either before or after the string, it prints the lines in either direction: # ifconfig | grep -C 2 loTX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ...
Search with Google-like Boolean query patterns using -% patterns with AND (or just space), OR (or a bar |), NOT (or a dash -), using quotes to match exactly, and grouping with ( ) (shown on the left side below); or with options -e (as an "or"), --and, --andnot, and ...
To match a pattern beginning with a dash, use the -e/--regexp flag. For example, to search for the literal '-foo', you can use this flag: rg -e -foo You can also use the special '--' delimiter to indicate that no more flags will be provided. Namely, the following is equivalen...
值得注意的是:ServiceMonitor 的 .metadata.labels 字段中的 team=node-exporter 必须与相应 Prometheus Agent 的 matchLabels 匹配。 让我们将 ServiceMonitor 创建于node-exporter namespace中: kubectl apply -f service-monitor.yaml -n node-exporter 观测 ...
