I need to count the number of times a character repeats in a string .
For example: How many times does the / character appear in the string below?
'/ file / program-files / test / dev / dev1 / Central.pdf.gz'
This string will be inside a $v_dir_relatorio variable.
I need the amount of bars to create a search logic for directories that the paths vary.
Another alternative is to remove the characters you do not want, using //[^\/] , after that just count the remaining characters:
v_dir_relatorio="'/file/program-files/teste/dev/dev1/Central.pdf.gz"
quantidade="${v_dir_relatorio//[^\/]}"
echo "${#quantidade}" # 6
echo $v_dir_relatorio | grep -o / | wc -l
echo to pass something to the pipeline, in this case $v_dir_relatorio
grep to search for a pattern, in this case the '/' character. The -o option prints each 'match' found on a line. wc to count. With -l it counts the number of lines, which matches the number of 'matches' found. In shell script (bash) one of the alternatives can be:
echo "/1/2/3/4" | grep -o '/' | wc -l
For your case:
v_dir_relatorio='echo "$CAMINHO" | grep -o '/' | wc -l'
I found other valid answers at: link
Already using Perl:
perl -nE 'say tr!/!!' <<< $v_dir_relatorio
The command tr (which transforms the set of characters of the first group into the corresponding one of the second) returns the number of characters found.
