I then used another regex-based Unix tool, the stream editor sed, in a little shell script to change all occurrences in those files from main(String *([a-z][a-z]*)[] to main(String[] $1 (the syntax used here is discussed later in this chapter). Again, the regex-based approach ...
It is intended primarily for medium to large AWK programs used in shell scripts. Each argument supplied via -e is treated as if it begins with an implicit @namespace "awk" statement. -E file --exec file Similar to -f, however, this is option is the last one processed. This ...

As usual, we can employ quotes in a specific manner to ensure a given shell variable is interpreted directly within the text of an AWK script: $ CHARS=23 $ printf 'Line 1.\nLine 2.\nLine 3.' | awk '/['"$CHARS"']/' Line 2. Line 3. In this case, to achieve the results fro...
For example, a shell script for COMMAND might look like: case "$1" in *.pdf) exec pdftotext "$1" - ;; *) case $(file "$1") in *Zstandard*) exec pzstd -cdq ;; *) exec cat ;; esac ;; esac The above script uses pdftotext to convert a PDF file to plain text. For all ...
Then, we implemented some solutions using theawkcommand. Finally, we presented a solution by writing a shell script to insert data in a file using the Bash loops and thegrepcommand.
