grep命令处理的文件的百分比或数量

Question

If I am searching/checking for an KeyWord/String using GREP command from 1000 files for example; then is there any option/way to see/display the percentage or number of files processed by the GREP command...?.

Just I would like to know how long further it will take to complete the search process.

Please help

Answer 1

try awk . This will print a messages suggesting the file number being processed, followed by the line matching the pattern. I have chosen the pattern here to be character p as that was easy for my testing. You can replace with any valid regex for your purpose.

awk -v PAT="p" 'FNR == 1 { n++; printf "Processing %d of %d files\n", n, ARGC - 1 >> "/dev/stderr"} FILENAME ~ /.gz$/ {print "Skipping gz file: ", FILENAME; nextfile} /PAT/'

Explanation

awk -v PAT="p" '
    FNR == 1 {                                # Every first line of the file
       n++;                                   # Counter for file being processed
       printf "Processing %d of %d files\n",  # Print message
          n,                                  # file number
          ARGC - 1                            # Number of files on CLI
          >> "/dev/stderr"                    # Redirect to stderr
    }
    FILENAME ~ /.gz$/ {                       # Skip gunzip files
       print "Skipping gz file: ", FILENAME; 
       nextfile                               # move to next file
    }
    /PAT/                                     # Pattern to print
'

UPDATE

Updated the code to skip the gunzip (.gz) files when processing.
