The backquoted form is the historical method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backs= lash character. Because of this the POSIX shell adopted the $(=E2=80=A6) fea= ture from the Korn shell. The patch was generated by the simple script for _f in $(find . -name "*.sh") do =C2=A0 sed -i 's@`\(.*\)`@$(\1)@g' ${_f} done Signed-off-by: Elia Pinto --- git-pull.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/git-pull.sh b/git-pull.sh index 6cd8ebc..cfc589d 100755 --- a/git-pull.sh +++ b/git-pull.sh @@ -108,7 +108,7 @@ do -s|--s|--st|--str|--stra|--strat|--strate|--strateg|--strategy) case "$#,$1" in *,*=3D*) - strategy=3D`expr "z$1" : 'z-[^=3D]*=3D\(.*\)'` ;; + strategy=3D$(expr "z$1" : 'z-[^=3D]*=3D\(.*\)') ;; 1,*) usage ;; *) --=20 1.7.10.4
